Retouching Teeth Whitening

I whitened my teeth several years ago and would like to retouch them before I have to get my dental crown. This way I can make it into the color I want. The problem is my dentist can’t tell me how to go about this. I’m hoping you can. My dentist has a 33% of whitening gel. Here are my questions. First, how many weeks should I use the gel? Second, for how many hours each day should I whiten?

Dear Audrey,

There are not specifics that work with teeth whitening like that. However, there are general principles. I don’t know exactly how white you want them. The most basic of these principles is that the longer you wear the whitening gel, the faster your teeth will whiten. If you wear them overnight, which is the most effective time to bleach, your teeth will whiten much faster than if you just wear the trays for an hour a day.

As an example, and this is most definitely not exact, if you wear them overnight, you could do in one week, what wearing them an hour a day would take you eight weeks. Again, not exact, and it depends on how white you want them.

The one sure principle, is something you have not asked. You will need to wait two weeks from the time you finish whitening until you match the crown color. This gives the whitening the time to settle to its final color before you start with the porcelain crown.

One thing to bear in mind here. If your dentist was not able to answer these basic cosmetic questions, then how can he or she provide you with a beautiful crown? You may want to at least make sure your dentist is going to do a temporary try-in and let you make sure everything matches in a way that is beautiful before permanently bonding them on. If you’re not happy with the crown, he should be willing to send them back to the lab.

Lemons for Teeth Whitening

Is it possible to use lemons to whiten your teeth? I read something on a website about this method. Before I tried it, I thought it would be best if I checked with a dentist before I did something I might regret.

Angie

Dear Angie,

Lemons

You were wise to write and ask. It is the citrus acid that is the problem here. A while back I looked into an at-home teeth whitening kit that someone asked me about. It contained a citrus acid rinse that the patient would start with. This would give the tooth a frothy appearance because the acid etches the teeth. Then, they would use a white pigment that they would attach to the teeth. For a short period the teeth would look much whiter. Unfortunately, because the citric acid etches the teeth, they will begin picking up stains fairly quickly and you will end up with teeth that look darker than when you started.

The second problem you will have as a result of using lemons is the damage that the citric acid will do to your enamel. Prolonged usage will thin out your enamel. Not only will this add to tooth sensitivity but will make you more susceptible to tooth decay.

My suggestion is to have your teeth whitening done safely, with a dentist. The materials they used are proven both safe and effictive. Additionally, they use a special tray custom fit to your bite. This will make sure the teeth whitening gel stays on your teeth while simultaneously protecting your gums.

Crest 3D Advanced White Toothpaste Gunk

I don’t quite know how to explain this but will do my best. I’ve been wanting to whiten my teeth but thought I would just try the whitening toothpaste first to see what type of results I can get. It’s leaving this weird white gunk on the inside of my lips about ten minutes after I use it that makes it look like my skin is ready to peel off. Is this common and part of the process?

Kelly

Dear Kelly,

Most whitening toothpaste that you purchase over the counter does not whiten your teeth the way that professional teeth whitening does. Your dentist would provide you with a gel that will penetrate the tooth and oxidize it from the inside out. Whitening toothpaste uses abrasives that scratch the surface of your teeth and scrub the surface stains off. While this can remove the stains temporarily it does damage your enamel which will cause it to pick up more stains at a faster rate.

I think the reason for the peeling skin you are experiencing is sodium lauryl sulfate, an ingredient found in this toothpaste. It has been known to produce side effects such as inflammation, skin irritation, and sloughing of oral tissues. I would stop using this because you are obviously having a reaction to it.

If you want to try a whitening toothpaste, I recommend you use Supersmile Toothpaste. This uses a protein pellicle to remove surface stains and will not damage your teeth. Bear in mind, that it will only remove surface stains, which is all that a toothpaste can do.

If you have years of stains on your teeth, you are better off with professional teeth whitening. Though it costs a little more, the results are massively better than anything else you’d get with an over the counter product, including something like whitestrips. If cost is the main issue, talk to your dentist and he or she may be willing to work with you on payment options.

Is Tanda Pearl Teeth Whitening Safe?

I have been doing some teeth whitening with a kit my dentist gave me but the trays hurt my jaw. I saw an advertisement for the Tanda Pearl Teeth Whitening System. They said with their special light that you only have to do the whitening for 5 minutes per day. My dentist has me doing it for an hour. I think only needing 5 minutes would really help my jaw pain. Do you know if this is legitimate?

Sally

Dear Sally,

teeth whitening trays
Professional teeth whitening trays

I am glad you wrote. I think I can help you. First, you should know that the whitening ingredient they use is legitimate. That will whiten your teeth. That being said, their light doesn’t seem like it is anything special and they shroud it in mystery which makes me distrust their claims about it. If it did have anything better than the Zoom light, they’d make a fortune marketing it to dentists. They do not, which makes me think it is more psychological than utilitarian.

There is something important to bear in mind, especially if you are having jaw pain. They do not use two separate trays, the way your dentist likely did. You should have something similar to what is pictured above. With the Tanda Pearl System, there is one tray that you have to hold onto with your teeth in order to keep it in. I believe this is going to cause you more pain than what you are experiencing now.

Some other considerations are the fact that the tray will not be custom fit to your bite. This means that the gel will leak out making the strength less effective. It also means your saliva will mix with the gel in the tray further weakening its effectiveness. Finally, the gel can also irritate your gums as it leaks out. You won’t want that either.

My suggestion for you is to first have your dentist look at your trays to make sure they were properly fit to your bite. If the trays are fine then you can simply whiten for a shorter amount of time. You don’t have to wear them for an hour. You can do a half hour or even fifteen minutes. Try lessening the time. I think that would be more comfortable for you than what this kit offers.

Premium Home Whitening Versus the Dentist

I want to whiten my teeth but I’ve been avoiding going anywhere with the surge of covid cases. I just feel like I need something to cheer me up. Looking online, one kit I see that has some positive reviews is Premium Home Whitening. How does this rank with what I’d get from my dentist? Will it actually whiten my teeth?

Gina

Dear Gina,

teeth whitening trays
Professional teeth whitening trays

I’ll start with the positive about this kit. The teeth whitening ingredient is valid and will whiten your teeth. So, if you decide to use this product and really stick with it, you could get some good results. That being said, I have some concerns.

Disadvantages to Premium Home Whitening

This first one I would not call a disadvantage as much as a red flag. The light they provide does nothing. It is simply a marketing ploy. Why not just sell the kit without it and lower the price. To me, that calls into question the integrity of the company and I’d wonder if the rest of what they list is true. For instance, is the whitening ingredient really the percentage they say it is?

The second is the whitening trays. These are not custom fit the way you would get with your dentist. Instead, you DIY them at home. This causes two problems with the whitening gel. Your saliva can get into the tray, which will weaken the strength of the gel. Now it will take more kits to do the same amount of work. In addition to that, your gel can leak from the tray. Not only does this further weaken the gel, but it puts your gums at risk of irritation. There have been cases where patients needed a root canal treatment as a result of an over-the-counter whitening kit because of this type of leakage.

My Recommendation

I would get your teeth whitening done with your dentist. In the long run, you should save money and it is safer. You mentioned concerns about COVID for not wanting to go in. Dentists are all taking extra precautions to ensure the safety of their patients, especially at this time. Something you could request is to ask to come at a time when they have fewer patients, that way you are not surrounded by as many people. Also, some patients have even requested they wait in their car and the receptionist just texts them when it is time to go back.

I hope this helped.

Dentist Can’t Match My Crown

I need some advice. I don’t know if the problem is the dentist or the lab, but my dentist cannot get my dental crown white enough to match my teeth. I’m new to the state and am using a different dentist than I normally would. However, this is my first dental crown so I don’t really know what to expect. I only came to him because of a dental emergency and he was available. I was in a car accident and had serious damage to a canine tooth as a result. He says he is using the whitest shade possible. I do whiten my teeth, but they don’t look unnaturally white. Just whiter than what he’s offering. It’s a noticeable difference though. Is it worth it for me to drive to my old state to get this to match or am I asking for the impossible?

Brooke

Dear Brooke,

I don’t think you’ll have to do anything as drastic as going to another state. I think I know what the problem may be here. Understand that this is mostly guess work, but I feel fairly confident with it. This dentist is probably a great bread and butter general dentist. He knows how to fix teeth and he does it well. However, he is more interested in the engineering factor than cosmetic work. He probably doesn’t really do any cosmetic work. This is the problem.

Old Vita Shade Guide
Old Vita Shade Guide

General dentists use a shade guide to help them match the crown they are making to your current shade of teeth (see above). He is probably using the same shade guide he’s always used. The problem with that is the popularity teeth whitening gained in the 90s. Teeth whitening does not just remove stains. It can also make your teeth whiter than even their original shade. That means the old shade guides were no longer as useful. Dental supply companies realized this and soon came out with an updated guide that included shades for whiter teeth (see below).

New Vita Shade Guide

I would ask this dentist for a refund and then go to a dentist who does more cosmetic work. They will have the updated guide and can match your teeth.

How Much Do I Need for a Smile Makeover?

I am a tad confused about something and hope you can help clear some things up. I want to get porcelain veneers but in order to do that, my dentist is insisting I also get teeth whitening and Invisalign first. I was under the impression that porcelain veneers can make your teeth look white and straight. My teeth aren’t really crooked enough to justify a full orthodontic case. I just have one front tooth that crosses over the adjacent tooth. Have I misunderstood this completely?

Theodora

Hi Theodora,

Porcelain veneer being added to a tooth

Let’s start with the teeth whitening. Whether or not this is useful to you depends on how many veneers you are getting. Very few people can afford to get a porcelain veneer placed on every tooth. That means the other teeth may need some whitening done in order to match your porcelain veneers. Most smiles are 8-10 teeth wide. If you’re only getting four or six veneers, you’ll want to whiten your teeth first to have everything blend naturally. The same goes for your bottom teeth. I doubt you want to spend money to veneer your bottom arch. In most cases, people get enough veneers on their top arch to have a beautiful smile and only whiten the bottom arch.

The Invisalign is a completely different story. Given the scenario you described to me, I don’t think you need orthodontics. Porcelain veneers done well can take care of that issue. The fact that your dentist is suggesting Invisalign tells me that he or she is not comfortable reshaping your teeth for the procedure. Don’t force his hand. Instead, find a cosmetic dentist who has done this lots of times and will be skilled getting it done.

Luster Premium At-Home Teeth Whitening

I don’t really feel comfortable with dentists but want to whiten my teeth. I saw an advertisement for a DIY kit call Luster Premium At-Home Teeth Whitening. It seems to have one of those light things that dentists use with teeth whitening. Do you know if it is safe? There are some good reviews, but these days it is hard to tell if they are legitimate.

Kristen

Dear Kristen,

teeth whitening trays
Professional teeth whitening trays

Looking at this particular whitening kit, I am glad you wrote before purchasing it. It won’t harm you, but you won’t be getting the whitening you think you are. True teeth whitening kits use a special peroxide gel to get your pearly whites looking youthful and bright again. Many over-the-counter kits have a legitimate ingredient, such as Crest Whitestrips. Though, by law, they are significantly weaker than what you would get with a dentist’s office.

Unfortunately, this kit doesn’t use a legitimate whitening ingredient. The whitening effect they achieve appears to be from a pigment in the zinc oxide. The pigment will stick to your teeth and make them look whiter, but only temporarily. The pigment will only last a few days. My suspicion is many of these positive reviews were written before the pigment wore off.

The light is another issue altogether. It is too weak to be of any effect even if they had a valid teeth whitening ingredient. It appears to be there for psychological effect. So, you essentially have a company using a bogus lamp that is supposed to aid the whitening, with an ingredient that merely colors your teeth.

If you are absolutely committed to doing this without a dentist, I suggest you use Crest Whitestrips. At least their product will work. It will cost you more in the long run to get the same results you would with a dentist, but it will work.

Dealing with Dental Anxiety

You mentioned being uncomfortable with the dentist. I wanted to make sure you knew dental anxiety is a pretty common thing and there are dentists equipped to help. Most dentists who enjoy working with and helping anxious patients will have a way to locate them on the internet by doing a search for a sedation dentist.

There are medicines available that will relax you in the dental chair and give you an anxiety-free and pain-free experience. I’ve found this has changed the lives of patients who were afraid to go to the dentist. Now they are able to get regular dental care and get the work done they’ve been avoiding for years.

Why do I have stains between my front teeth when I have porcelain veneers?

I am so sad about my porcelain veneers. I got them a little over a year ago and they were a dream come true.  My smile was exactly what I wanted.  My problem is I’m getting some dark spots in between my front teeth, almost like a line. Have I somehow ruined my new teeth?

Terry in Honolulu

Dear Terry,

Porcelain veneers are nice because they can not only make your smile more beautiful, but they are pretty stain resistant.  Teeth whitening is not needed or suggested when you have porcelain veneers.

So why are there stains on your porcelain veneers?

There is a glaze that is applied to your new porcelain veneers when they are made. The glaze determines the shine of your teeth so they look natural, not dull.  That glaze is also a big factor in the stain resistance of your veneers. Your teeth shouldn’t stain unless that glaze is somehow compromised. This can happen if your dentist uses a power polishing machine at the office or an inappropriate fluoride treatment.

There are several foods that cause stains on teeth. Coffee and juices are just a couple, not to mention how smoking stains your teeth.  If your porcelain veneers were absorbing stain because of a problem with the glaze, it would be more across the surface of the tooth, not just in one line between the teeth.

Porcelain veneer being added to a toothBecause of the area of stain you describe, it’s likely that your problem is where the veneer meets your tooth. This could be caused by a gap between your tooth and the porcelain veneer that wasn’t bonded well and has allowed the stain to enter there.

It could also be that there was some bonding composite on that line that wasn’t polished well. The stains may just be on that bonding agent. If that’s the case, it’s just a matter of repolishing that area.

In either case, a return visit to the dentist who put on your porcelain veneers would be a good place to start.  Hopefully, it’s just a simple polishing issue. Really, it’s a good idea to schedule regular maintenance appointments for your veneers. It will help maintain their stain-resistance and increase their lifespan.

Can I whiten a bonded area on my tooth?

I had a little black space near my gums covered with dental bonding a few weeks ago. I love having that space filled because I really self-conscious about it. It looks like my bonding is turning yellow, though. My husband says it’s not, but I swear it’s more yellow than it was when I got it put on. I typically brush with baking soda and that’s not helping.  I have a tooth whitening tray from my dentist a year ago. Should I try it on my bonding?

Amelia, Four Corners area

Amelia,

Baking soda is not your best option on dental bonding or porcelain veneers. It is very abrasive and can cause damage to the glaze on the bonding or veneers. The baking soda may be what has made your bonding turn yellow. If the polish has been compromised, that area may be more susceptible to stains from food or drinks, such as berries, coffee, or tea.

The problem could just be the bonding material itself.  If your dentist wasn’t experienced in cosmetic dentistry, there’s a chance that the materials he used weren’t quality materials. It may have caused the area to yellow.

How do I fix my yellowed bonding?

As you said you had this bonding done a few weeks ago, you should return to your dentist and ask about the coloration of your bonding.  Ask if they can repolish that area. Unfortunately, as with porcelain veneers, no whitening will work. Actually, with bonding, whitening can actually make that area look worse because it will whiten the tooth around the bonding and leave the bonded area the color it is.

If you can resolve the coloring issue with your bonding with your dentist, look for a specialty toothpaste designed specifically for bonded areas or porcelain veneers, such as Supersmile toothpaste. If your dentist can’t remedy this, you may need to see another cosmetic dentist. That area may not need to be completely redone, but may be corrected with just better materials.
