Understanding the Mechanics of Teeth Whitening

Teeth whiteningJust about everyone desires a whiter set of teeth. Men and women of all ages seek teeth whitening treatments to achieve picture perfect smiles. Whether it involves dropping by your dentist’s office or concocting home remedies, whitening solutions are a “thing”—they have been for a long time.

Teeth whitening is an effective solution for discoloured teeth. Patients who undergo the treatment can testify on moderate to substantial improvements. Edinburgh Dental Specialists says of the procedure: “Teeth whitening is a successful and simple method of lightening the colour of your teeth. The degree of whiteness achieved will vary from patient to patient and with the type of bleaching process chosen.

In-office teeth whitening is a popular option for teeth whitening aficionados. It is considered as the most popular cosmetic dental procedure in the world today. If you are interested in whitening your teeth, here are the basics you need to know:

Understanding the nature of stains

Stain formation causes teeth discolouration. There are numerous factors that contribute to the formation of stains: smoking, drinking habits, bad oral hygiene, aging and medical history. There are two types of stains:

  • Extrinsic stains: These types of stains are located in the tooth pellicle, a film composed of proteins found in that saliva and which covers the enamel.
  • Intrinsic stains: located beneath the enamel surface; aging is a primary cause for this type of stubborn stains.

Particles from food, drinks and tobacco build up on the tooth enamel. Unremoved stain causes yellow and dull teeth.

Removing surface stains

Teeth whitening procedures use chemical and physical means to remove stubborn surface stains. Dentists use abrasion, chemical stains, removal or disruption during treatment to destroy stains on top of the enamel.

This type of treatment involves high-concentration peroxide gels. Dentists protect your gums with rubber dams before applying the solution. The peroxide remains on teeth for 15-20 minutes, usually adding up to an hour. Dentists advise patients with stubborn stains to return for one or more bleaching sessions.

Teeth whitening maintenance

Teeth whitening, despite its effectiveness, is not a permanent solution for teeth discolouration. Regular maintenance is required. For a longer period with more sparkling pearly whites, dentists will recommend the following:

  • Refraining from dark-coloured food and beverages
  • Home remedies and maintenance
  • Usage of straws for dark coloured beverages
  • Excellent oral hygiene practices

Teeth whitening is a complicated procedure that yields great results. It is your key toward a brighter and whiter smile.
