However, in other cases, it is possible that we are not entirely happy with the color of our teeth well because we have some teeth or poor aesthetics because a tooth may have darkened after a root canal or dental trauma.
If for whatever reason you want your teeth whiter have a better appearance and should know all the options currently available.
Types of Tooth Whitening
Teeth whitening can be:
- internal tooth whitening (in devitalized teeth only)
- external tooth bleaching (the most common)
Also, depending on where the treatment takes place we can distinguish between:
- Whitening in the dental clinic
- Whitening at home
- Mixed Media whitening (in clinic and at home)
External Teeth Whitening
Currently tooth whitening is based almost exclusively on the use of whitening products with different concentrations of carbamide peroxide in their composition.
These products, activation (usually by heat or a special light) having the property of releasing hydrogen peroxide, which is filtered through reaching enamel dentin. Dentin is the internal tissue defining the tooth color and the effect of hydrogen peroxide undergoes oxidation resulting in bleaching of the dental tissues.
The degree of whitening varies from one patient to another and will depend upon the particular color of each set of teeth. Each person has a particular color to be reviewed by the professional to determine expectations whitening.
Perform an accurate forecast on the final color is complicated in some cases, in these circumstances it is best to perform the whitening gradually over a period of time longer than could reach six months. In this way the whitening will become more gradual and safe in achieving the desired result.
What should you ask your dentist?
In general all whitening techniques work but we know in our particular case if bleaching is indicated and make sure we are going to apply a good product reputable and proper technique.
The dentist can tell what whitening method is best suited for you. Whiteners do not correct all types of discoloration. For example, yellowish teeth will likely be better than more teeth whitened brown or grey tones. One must also know that bleaching will not be uniform if your front teeth have some rebuilding or sealed with composite. Note that the whitening product does not affect the colour of these materials and therefore stand out more if we subject our teeth to tooth whitening. In these cases it is interesting to investigate other options such as porcelain veneers or composite.
In cases of tooth hypersensitivity treatment should always be done in order to control clinical minutely what parts of dentin are going to be treated and to isolate and protect areas where it is not necessary to apply the product.

What is tooth whitening at home?
Without professional supervision
Bleaching can a person with the means at its disposal has a limited effect on the best.Often the money is wasted in toothpastes and mouthwashes but do not remove stains tooth whitening. These products help remove surface stains through the action of slightly abrasive agents but, unlike the bleaching solutions used in the dental clinic, these products do not alter the intrinsic color of teeth.
With professional supervision
Two-ferrule (one for the upper teeth and one for lower) flexible and transparent structure to fit the shape of the patient’s teeth are created in the laboratory.
The patient is given a whitening kit with bleaching product along with the two splints and instructions for use.
Following the instructions on the whitening product is applied splint and it is placed in the mouth. It is important to clean your teeth well before settling splint. The timing and duration of application of the splint in the mouth depends on several factors (concentration product, patient characteristics, etc.).
A review will be done in the office each week to assess the progress of treatment and the colour obtained and if there are any problems will act accordingly.
You should talk to your dentist if any side effects become too bothersome. The teeth may become more sensitive during treatment, in most cases; this sensitivity is temporary and should be reduced after treatment ended. Some people may also experience irritation of the soft tissues of the mouth. If you are concerned about these side effects should talk to your dentist for advice.
What is the whitening in the dental clinic?
If you are having a teeth bleaching, your dentist may suggest you perform the treatment at the dental clinic. This procedure usually requires more than one visit to the clinic and each session can last from 30 minutes to about an hour.
During the whitening session at the clinic will be necessary to protect the soft tissues of the mouth with a gel or a splint. The bleaching agent is then applied to three or four pauses to renew the bleach product applied to the teeth.
In some cases the bleaching agent is activated by heat, light or special laser. In other contribution does lighting and lack of any kind that are activated when mixed with a catalyst. Lots of advertising that emphasizes the activation method used (laser, plasma lamp, etc..), It really does not matter since the active ingredient is the same in all cases (hydrogen peroxide). What is important is product quality and good craftsmanship to prevent unwanted side effects (root resorption, pulpitis, chronic hypersensitivity, etc.).
Precautions during tooth whitening
If whitening is done exclusively in clinical, follow your dentist’s advice.
If we are to make full or partial treatment at home is advisable to minimize certain habits and meals or drinks with pigments (coffee, tea, snuff, etc..). It should be noted that during this phase the teeth are more susceptible to the effect of external coloured pigments.
Precautions after finishing the bleaching
If sensitivity to cold or minor annoyances should not worry because in most cases are transient.
After treatment we can use mouthwashes and fluoride toothpastes normal (but not coloured for at least 15 days).
For 4 to 5 weeks is advisable to avoid fizzy drinks, acidic foods and any food product or causing stains (colas, citrus, spinach, red wine, coffee, tea, etc..). At this stage the tooth is more prone to colour but then can make normal life.
The final result can remain in the mouth for several years (depends on each person’s teeth, your care and habits). After this time we lose whitening but never back to the original colour, our teeth will always be whiter. In these cases it is advisable one or more booster sessions in the dental clinic to recover the desired whitening.
