Causes of tooth discoloration
Over time, your teeth can go from white to not-so-bright for a number of reasons:
If you’ve been hit in the mouth, your tooth may change color because it reacts to an injury by laying down more dentin, which is a darker layer under the enamel.
Tooth darkening can be a side effect of certain antihistamines, antipsychotics and high blood pressure medications. Young children who are exposed to antibiotics like tetracycline and doxycycline when their teeth are forming (either in the womb or as a baby) may have discoloration of their adult teeth later in life. Chemotherapy and head and neck radiation can also darken teeth.
There are two general approaches:
- In-office bleaching – also called chairside bleaching or power bleaching
- tray-based tooth whitening systems supervised by dentist
- At-home bleaching which includes; Tooth paste and take home bleachings
in-office-based tooth whitening procedure: Lsaer treatment
In offic teeth whitening is administered in a dental office exclusively, a protective gel or guard is positioned over the gums before the bleaching agent is applied, the bleaching agent is applied directly to the teeth, and heat generated by a laser enhances its effectiveness while ultimately speeding up the process. This procedure uses a strong bleaching gel that the laser activates and enhances for quick, dramatic results. it is a hydrogen peroxide gel that ranges from 25 to 40 percent in concentration levels. With these high concentrations, special precautions are taken to reduce tooth sensitivity, as well as protect the lips, gums and other oral tissues from being damaged. The affects from this bleaching process should last from 6 months to a year. This will greatly depends on the types of foods and drinks you include in your everyday diet. This also greatly depends on your general dental hygiene habits.
tray-based tooth whitening
For the more traditional types of teeth whitening procedures using tray-based tooth whitening systems provided through your dentist’s office, the first step involves filling a mouth guard-like tray with a gel-like whitening solution - which contains a peroxide-bleaching agent. This tray is then placed over the teeth and worn for a period of time, generally from a couple hours a day or every day during the overnight for up to 4 weeks and even longer (depending on the degree of staining and desired level of whitening).
All toothpastes help remove surface stains through the action of mild abrasives they do not contain bleach. they can lighten your tooth’s color by about one shade. In contrast, light-activated whitening conducted in your dentist’s office can make your teeth three to eight shades lighter.
The peroxide-based whitening gels and Whitening strips are over the counter bleaching products that applied to the surface of the teeth. Instructions generally call for twice a day application for 14 days. Initial results are seen in a few days and final results are sustained for about 4 months.
The advantages of in-office bleaching procedure compared to At-home bleaching
Strength of bleaching agent
over-the-counter home use products and dentist-supervised at-home products usually contain a lower strength-bleaching agent (from 10% carbamide peroxide–which is equivalent to about 3 percent hydrogen peroxide -- up to 22% carbamide peroxide). In-office, professionally applied tooth whitening products contain hydrogen peroxide in concentrations ranging from 15 to 43 percent. Although some teeth lightening will be achieved by home bleaching products but, their degree of whitening is much lower than results achieved with in-office or dentist-supervised whitening systems
With dentist-supervised at-home bleaching products, your dentist will take an impression of your teeth and make a mouthpiece tray that is customized to exactly fit your teeth. This customization allows for maximum contact between the whitening gel, which is applied to the mouthpiece tray, and the teeth. A custom-made tray also minimizing the gel's contact with gum tissue.
Over-the-counter whitening products do contain a mouthpiece traythat the fit will not be exact. It can irritate the gum and soft tissue by allowing more bleaching gel to seep onto these tissues. With in-office procedures, the bleaching agent is applied directly to the teeth.
Additional protective measures
In the office setting, your dentist will apply either a gel to the gum tissue or use a rubber shield (which slides over the teeth) prior to treatment to protect your gums and oral cavity from the effects of the bleaching.
Speed of the bleaching process
Dentist-supervised at-home bleaching and over-the-counter bleaching products typically need to be applied every day for 1 or 2 hours or every overnight for up to 4 weeks. In-office bleaching provides the quickest and most effective way to whiten teeth. With in-office bleaching, the whitening product is applied directly to the teeth. These products can be used in combination with heat, a special light, and/or a laser. The light and/or heat accelerate the whitening process. Results are seen in only 1, 30- to 60-minute treatment.
To achieve dramatic results, however, several appointments are usually needed. With laser-enhanced bleaching, however, dramatic results can be seen after the first treatment.
Supervised versus unsupervised process
Dentist-supervised at-home bleaching and in-office treatment offer additional benefits compared with over-the-counter procedures. First, your dentist can perform an oral examination and consider your complete medical history, which can be helpful in determining how your teeth became discolored and if bleaching is an appropriate course of treatment based on your type of stains and number, type, and location of restorations. your dentist will likely to make sure the customized tray is fitting properl, and to generally check on how the teeth whitening process is proceeding. With over-the-counter bleaching products, you are on your own
How long will the in office treatment last?
This will very from client to client and greatly depends on the types of foods and drinks you include in your everyday diet. This also greatly depends on your general dental hygiene habits. The affects from this bleaching process should last from 6 months to a year.
