Why do teeth get darker?
- Wether it be food that we eat or things that we drink, our teeth are very sensitive to darker colors in our diet.
- Most often the things that make teeth darker are coffee, tea, red wine, smoking and dark fruits.
- Very fine particles from these drinks and foods work there way into the inner surface of the tooth, darkening it and causing the outside of the tooth to look darker as a result.
how does teeth whitening work?
- The whitening solution gently removes the very fine particles and organic debris that accumulates under the surface of our teeth.
- This cleansing process lightens the inside of our teeth, in turn allowing the outside part of the tooth to appear more white.
Is teeth whitening safe?
- It is always best to check with your dentist before starting teeth whitening treatments
- The most common side effect from whitening is tooth sensitivity.
- This is caused because the food and drink particles that were causing the tooth to become darker actually acted like a barrier from the tooth to various stimuli.
- When the barrier is removed, the tooth undergoes an initial shock to new stimuli, most notable hot and cold drinks as well as cool air.
- This sensitivity is very temporarily and usually last a few hours to a couple days
What type of whitening is available?
- There are two popular teeth whitening options available through your dentist.
- The first, in-office teeth whitening, produces a significant color change in your teeth in a short amount of time, usually within an hour.
- The procedure is done at the dentist's office by applying a high-concentration peroxide gel on the teeth after they have been protected with a special shield.
- The second method, involves the use of take home whitening kits.
- These whitening kits are purchased from your doctor for use at home.
- The strength of the gel used in these kits is lower than that used for in-office bleaching, and thus the gel can be applied for longer periods of time.
- Usually the trays are worn a couple hours a day for a few days or weeks depending on the product.
- Its best to consult your dentist to understand which whitening option is best for you.
