Does teeth whitening damage my teeth?


Among the most frequently asked questions we get at Ringmer Dental is “does teeth whitening damage the enamel?”

The conclusive answer is NO, teeth whitening gel will NOT damage or harm your tooth enamel.

Enamel is considered the hardest tissue in the human body. Enamel consists of tiny tubules that can only be viewed under high magnification. Even though enamel is the outermost layer of the tooth, it is the layer of tissue beneath the enamel that absorbs most of the stain, called dentin. To achieve successful whitening, the product flows through the enamel tubules and begins to lighten the underlying stained tissue.

  • Why does teeth whitening cause sensitivity?

Blog_Img_2021_06_01_002Whitening products can cause temporary tooth sensitivity. As the whitening gel undergoes its natural process from active to inactive, the tubules are left open and exposed, known as dehydration. The tubules are quickly remineralized by organic material found in saliva. During this time, it is important to avoid consuming any food or drink containing colour. Until the tooth is completely rehydrated it will absorb any colour of food or liquid it is exposed to. At this time, it is also suggested to stay away from extremely hot and cold along with sweet and salty substances, to avoid possible irritation of the nerve tissue.

Although it takes a very short time to dehydrate, re-hydration of the teeth can take hours. Tooth dehydration can be identified by white spots on the surface of the tooth. As the tooth becomes re-hydrated the white spots will disappear. If you experience sensitivity while teeth whitening discontinue until sensitivity is no longer an issue.

  • How long will the results last?

Blog_Img_2021_06_01_003How long the results will last will depend heavily on your lifestyle. If you are a smoker, drink a lot of tea or coffee and eat staining foods your teeth will not remain as white for as long. Normally it will be necessary to top up your whitening every 1-2 years to keep your teeth looking their best.
