Lemons and Teeth Whitening

Posted on by .

Is it possible for me to whiten my teeth at home with lemons? I read about it on a natural health website, but wanted to verify before I wasted a bunch of lemons or, even worse, damaged my teeth. I have not had much success with the over the counter whitening kits and I really want white teeth but my dentist only does Zoom, which is out of my budget.

Dear Megan,

Lemons

I am so glad you wrote. It was very wise on your part to verify something you read on the internet. While lemons could temporarily make your teeth look a bit whiter, eventually they will actually end up looking darker. This is because lemons have citrus acid. When that acid gets onto your tooth enamel it will micro etch the surface of your teeth. Those etches will cause your teeth to pick up stains much faster. With continued use, you could weaken the enamel of your teeth. You will find that people who suck on lemons have the same problem.

This is the same issue that happens to patients who are suffering from bulimia. The acidic nature of vomiting means that their teeth are slowly wearing away because of all the acid.

If you are determined to use an over the counter whitening kit, Crest Whitestrips do work, but you have to buy a LOT of kits to get the same amount of teeth whitening you could with a dentist.

If you want professional strength teeth whitening but do not want Zoom, you could go to another dentist just to get your teeth whitening kit and get started then return to your dentist for your regular dental care. Be aware that most dentists will make you get a cleaning done before they will whiten your teeth. This is to ensure there are no problems with your teeth. It’s also to make sure there is no plaque that can lead to splotchy results. You can just tell them that you are happy with your dentist for your regular care, but do want to whiten your teeth.

Porcelain Veneers and Teeth Whitening

Posted on by .

I need to whiten my teeth. Well…I want to whiten my teeth. What worries me is that I have porcelain veneers on only four of my teeth. It’s the teeth next to the porcelain veneers that need the whitening. My smile is about eight teeth wide. I wish I had the money to do more veneers so they’d all match but I didn’t. I want to whiten the teeth to match but I’m worried that the whitening gel will hurt the porcelain veneers. Will I damage them if I use something weak like Crest Whitestrips?

Teeth Bleaching Trays

I am glad you wrote. I wish your dentist would have whitened your teeth before doing your porcelain veneers. That is pretty standard operating procedure when a person can’t get enough veneers to cover the width of their smile. The good news is, while it won’t be as easy, it is still possible to get them whitened.

Crest Whitestrips will not do any damage to your porcelain veneers. In fact, neither will professional strength teeth whitening. If you decide to use the Whitestrips, you need to be aware of some limitations. First, they’re not very big. In fact, they’ll only cover your first six teeth. With four of them being veneered, that would mean you are wasting a significant amount of whitening. With them being only a fraction of the strength of professional whitening, I don’t think you’d be truly satisfied with them.

My suggestion would be to have your dentist make you custom fitted trays that can be shaped around your porcelain veneers. This will enable you to whiten those teeth at full strength, while under the care of a professional. Plus, you can keep the trays and use them for touch-ups every couple of years. Then, you’ll only need the inexpensive gel.

Luster Premium Teeth Whitening

Posted on by .

I received an advertisement for Luster Premium Home Whitening. It’s a little cheaper than what my dentist’s office quoted when I called them so I am wondering if it actually works and if it is safe.

Dear Emma,

I periodically review these type of things at patients’ requests. While they all have downsides in comparison to professional teeth whitening, most of them have a valid whitening ingredient. In the case of Luster Premium, that is not true. There is not a valid whitening ingredient in this product. The only whitening that takes place with this is due to a pigment in their “super whitener” — zinc oxide. This sticks to the teeth and makes the teeth look temporarily whiter. It does not actually whiten them. The pigment wears off. I am convinced that the positive reviews they have are from people who saw the whitening difference from the pigment and wrote the review not realizing it would quickly wear off.

If cost is the only thing keeping you from getting teeth whitening done by your dentist, you could put some money aside every few weeks or possibly talk to your dentist to see if he or she is open to allowing you to have a payment plan with them. If they say no and you are anxious to do it right away, an over the counter product that works is Crest Whitestrips. It is much weaker than the type of whitening you would get with your dentist but it will work. Another issue is it will only cover the front six teeth. Most smiles are at least eight to ten teeth wide. If that is you, you can use extra strips.

Honestly though, by the time you purchase enough kits to get your teeth really white, you would have spent less money if you would have just saved up and had it done right with your dentist. Plus, you can keep the whitening trays and, in future years, when you need a touch up you will just need to purchase the gel which isn’t nearly as much money.
