Side Effects of Bleaching Teeth
Teeth bleaching, or teeth whitening, is one of the most widely requested dental procedures. It has traditionally been performed in dentist's office, but can now be done by means of home bleaching kits, which can be purchased over the counter at a pharmacy and or drugstore. A number of effects that can result from bleaching teeth. Does this Spark an idea?
-
Sudden Sharp Pain
-
Some people who use bleaching trays to whiten their teeth have reported experiencing sudden, piercing pain in their teeth. The sharp pains are persistent, and usually last for a few minutes at a time. Dentists call them zingers. The bleaching trays are prescribed by the dentist, and are custom-molded for each individual patient.
Tooth Damage
-
Teeth bleaching can cause damage to the teeth. Prolonged use can cause the tooth enamel to take on an unnatural, bluish tinge and give them a translucent look. Furthermore, if the patient has an unfilled cavity, the bleaching chemicals may seep in and cause internal damage to the root of the tooth. In some cases, a root canal may need to be performed on the damaged tooth.
-
Dentin Hypersensitivity
-
Another side effect of teeth bleaching is dentin hypersensitivity. This is usually a temporary side effect, and it tends to result in sudden, sharp pain when you eat very cold or hot food and drinks, or when you breathe in cold air. When heightened sensitivity results from teeth bleaching, consult with your dentist, who can prescribe a lower concentration of the bleaching gel.
Overbleaching
-
Some people overuse teeth bleaching products, applying them longer or more frequently than recommended. This has harmful side effects, including great pain, gum irritation and tooth discoloration. The recommended bleaching regimen for bleaching trays and over the counter home kits is usually two weeks long. Furthermore, any bleaching method, including power-bleaching in a dentist's office, should not be done more than twice a year.
Carcinogenic
-
Most teeth-bleaching products have hydrogen peroxide as their active ingredient. This chemical is a carcinogenic, and may potentially result in oral cancer. If there is leakage from the bleaching tray into the mouth, the hydrogen peroxide releases carcinogenic compounds called "free radicals," that can cause cancer of the tongue. The American Dental Association (ADA) states that further studies need to be conducted to prove link a between teeth bleaching products and cancer.
