A smile is the way we let people into our lives from the first moment, a smile is our business card to the world, what if your smile is not what you would like it to be? Teeth discoloration is very common and it can be caused by many factors. In cosmetic dentistry whitening is a common, easy and not at all expensive procedure. Stains and decay in teeth may be caused not only by poor hygiene but for massive consumption of caffeine, tobacco, candy, soft drinks, ice chewing or even bad stains and discoloration can be provoked by misuse of tetracycline either by your mother during pregnancy or given to you while in early stages of a person’s life.
In dental whitening procedures can be accompanied by a nice relaxing trip to the beach to get ready to go back home, improving that always avoided visit to the dentist with something more peaceful than just cosmetic procedures.
BEFORE AFTER
What Factors Affect the Color of My Teeth?
Some people are born with teeth that are more yellow than others. Others have teeth that yellow with age. Your natural tooth color can also be affected by many factors. Surface stains (called extrinsic stains by dentists) and discoloration can be caused by:
- Tobacco (whether smoked or chewed)
- Drinking coffee, tea, or red wine
- Eating highly pigmented foods such as cherries and blueberries
- Accumulation of tartar deposits, which result from plaque that has hardened
Internal stains (called intrinsic stains by dentists) can be caused by:
- Treatment with the antibiotic tetracycline during the time when teeth are forming
- Yellowing or graying of the teeth as part of the aging process
- Trauma to the teeth that may result in the death of the tooth's nerve, giving the tooth a brown, gray or black color
- Ingesting too much fluoride when teeth are forming (from birth to age 16), which gives teeth a "mottled" look.
What are Ways to Whiten Teeth?
Thorough cleanings by a dentist or hygienist will remove most external staining caused by food and tobacco. Using a whitening toothpaste can also help remove these surface stains between dental visits. If stains have been present for years, you may need to have your teeth professionally whitened to remove these more stubborn external stains.
Internal stains can be bleached, bonded or capped (crowned). While each of these methods is safe and effective, your dentist will recommend which treatment is appropriate for you depending on the state of your teeth and the results that you wish to achieve. Your dentist will consider:
- The degree and type of staining
- How much of the tooth structure is remaining (Is the tooth heavily filled? Are changes to the shape of the teeth needed or desired?)
How Does Tooth Whitening Work?
Whitening (bleaching) can be done either in a dentist's office or at home, using a system dispensed by your dentist. Both methods use tooth-bleaching gels that oxidize out the stain. It's not uncommon for teeth to become slightly sensitive during the whitening process.
- At-home whitening
At-home whitening is the more popular approach today. Your dentist takes an impression of your teeth and makes a custom-fitted tray, which you fill with a whitening gel and wear up to two hours daily or at night for about two weeks. Many whitening kits prescribed by dentists today contain a solution of 10-15% carbamide peroxide. When done under the supervision of your dentist, at-home whitening is very effective.
- In-office whitening
Less frequent and more expensive, this procedure takes from 30 minutes to one hour per visit, and you may have to return for several visits to achieve the desired whiteness. To protect your mouth, a gel-like substance may be applied to your gums and a rubber "shield" may be placed around the necks of the teeth. An oxidizing agent (the bleaching solution) is then applied to your teeth. Sometimes, a special light is used at five-minute intervals to help activate the whitening agent.
