There are so many reasons why your teeth become stained. Darkly colored foods like coffee and tea, acidic foods like citrus and fruit juices, smoking and tobacco, or even antibiotics like tetracycline all lead to stained tooth enamel. Due to these factors, teeth whitening methods have been used by dentists all over the world to counter teeth discoloration.

Tooth whitening is otherwise known as dental bleaching. There are various methods by which teeth whitening is achieved. Chemical methods are the use of bleaching strips, pens, gels, lasers and natural bleaching. Dentists usually use hydrogen peroxide or carbamide peroxide to oxidize the enamel surface and remove superficial as well as deeply embedded stains. Mechanical methods in contrast, are the use of whitening toothpastes that help remove superficial stains on the surface of teeth.

While these methods have been used throughout the years, there have also been teeth whitening side effects which people out there ought to know. When high concentrations of oxidizing agents come in contact with other unprotected tissues like mucous membranes in the mouth, chemical burns may develop. They may even bleach or discolor these areas. You can also have excessively bleached teeth known as hyperodonto-oxidation. Yet, some may experience rebound bleaching. This means that instead of a whitening effect, it can cause further darkening of teeth.

Bleaching agents need to have the right amount of concentration in order to get the desired result. Otherwise you may experience these side effects.

Long term exposure to home bleaching treatments may also cause brittle teeth because of reduced enamel. There is increased tooth sensitivity and mild irritation in the gums, too, as temporary side effects of bleaching.

Due to these, bleaching is not recommended for people under the age of 16. There is increased risk for tooth sensitivity during these ages because the pulp chamber containing the nerves is enlarged. It is also not advised for pregnant women or lactating mothers.

When ingested, bleaching products may cause nausea, vomiting, or burning sensation in the esophagus.

A more dangerous study in Georgetown University even reveals that hydrogen peroxides can be a risk factor for tongue cancer.

While teeth whitening seem an easy procedure, you probably discovered that it is far from that. After you have read about all these, it is important to note that tooth whitening needs an expert opinion. This means that people should consult with their dentists first before trying chemical methods of dental bleaching. When you have your teeth bleached in dental clinics, dentists protect the gum tissues and mucous membranes from unwanted spillage of bleaching agents. This way, you are ensured that you won’t get unnecessary white spots on these areas.

Bottom line is this. Home whitening systems work best at giving you your best smile when you know the possible risks that go with them, and when you have previously consulted a professional help. You definitely do not want to end up maintaining a zipped mouth just because of teeth whitening side effects, isn’t it? So find the best whitening treatment for you.
