Why You Shouldn't Whiten Your Teeth
The number one thing all patients are interested in is whitening. I cannot tell you how many times I have had patients come in and only want to know about whitening when they needed a lot of extra work done. Also, many of these people wanting whiter teeth do not brush and floss daily and most of the time their yellow teeth are due to the fact they have so much plaque on their teeth.
So, what is so bad about whitening? Well for starter all whitening tooth pastes have abrasives in them which is scraping a layer of enamel off the tooth. This causes people to have sensitive teeth to hot or cold because they are taking an extra layer of protection away from the pulp. Thus, this is creating more problems for patients.
Also, I have seen many patients who have had cavities (which are black spots on the teeth) or demineralization (starts of cavities which are a chalky white spots on teeth) only want to have whiter teeth and are not interested in fixing their other problems. These spots will not get whiter without fillings or the proper treatments.
Lastly, whitening does not mean all your teeth will all be the same color. If you have fillings or crowns, those shades were chosen to match your current tooth color. The bleach in whitening toothpastes or trays do not whiten those fillings or crowns. So, while the rest of your teeth are getting whiter, you will have a few dark spots or a darker tooth. Whitening also causes problems when going to add new fillings or crowns. If you whiten your teeth too much, there are not shades of filling material or crowns which are that white. Thus, when you get that tooth fixed, it will not match the rest of your teeth.
Be smart before you whiten, always ask your hygienist for whitening advice!
