Dental whitening treatment is one of the most sought-after dental aesthetic services, which is a reaction to the increasing importance that contemporary society attaches to the outward appearance. Under these circumstances, it is not surprising that teeth whitening is a procedure specifically required by people under the public eye.
These cosmetic treatments differ in effectiveness, cost, durability and side effects, but tooth whitening generally refers to the application of peroxide compounds to the tooth, such as hydrogen peroxide. These agents penetrate the enamel and dentin gradually over time.
The degree of whitening of the tooth varies depending on several factors: the type of stains, the concentration of the whitening agent in the product used, the length of time the whitening agent acts on the tooth, and the frequency with which the treatment is repeated.
There are a few necessary steps before a teeth whitening treatment. First of all, the dentist should determine whether the patient is a good candidate for this procedure: teeth whitening is not recommended for pregnant or nursing women, people with gum disease or dental erosion, children under 15 and those with very sensitive teeth or someone allergic to peroxide.
We must also keep in mind that whitening has no effect on implants, crowns or any other type of tooth that is not natural. If you have a tooth-colored filling, whitening will only work on the tooth surface, not on the lining material.
Applicants for teeth whitening are those who have yellowish spots on the teeth or brown stains caused by coffee, tea, alcohol or medication.
The more the color of the teeth moves from yellow to gray, the more difficult it is to remove the stains. If you expect that right after treatment you will instantly enjoy bright white teeth, you may be disappointed. Whitening involves increasing the whiteness by a few degrees and the final result depends on the nature and severity of the stains on the teeth.
The whitening procedure performed by the dentist has the highest efficiency because the highest peroxide concentration is used: up to 38%. The treatment can take about 3 sessions, and after that, the patients will have teeth with up to 3-8 whitish shades brighter. The result of whitening lasts for an average of 2-3 years but can be repeated after this period.
The whitening treatment in the dental office proceeds as follows: the doctor isolates the gums to protect them (with a gel or rubber dam) and then applies the peroxide gel to the external surface of the teeth. Then, a special light (type of laser) is projected onto the dental surfaces for 30 to 60 minutes. Laser tooth whitening is considered to be the most effective and safe whitening treatment, but it is also the most expensive.
Dental whitening treatments are considered to be safe dental procedures when properly performed by professionals.
However, there are special cases when some unpleasant effects occur. These include dental hypersensitivity and gingival irritation. Another unpleasant effect is the uneven coloration of teeth – this occurs when the patient also has artificial teeth, only the natural ones have a whiter color.
Maintaining the whiteness of the teeth after the treatment requires a special effort: avoiding colored foods and drinks, impeccable oral hygiene and continuing treatment in the home with home-based treatment. Here is a website that provides more valuable information on Teeth Whitening.
Causes Leading to Yellowing of Teeth:
The color of teeth is affected by eating as well as other factors. We list 7 situations that affect dental staining:
1. The color of teeth is genetically acquired.
2. The teeth turn yellow with aging.
3. Smokers, as well as consumers of coffee, tea, red wine, blueberry juice or red beet can suffer from dystonia (yellowing of the teeth).
4. Child’s teeth are affected by some drugs, metals and even some toothpaste or mouthwashes.
5. Blood diseases or some liver problems can affect dental color.
6. Fluoride overdose leads to a condition called fluorosis, which is manifested by the appearance of white spots on the surface of the teeth.
7. Antibiotic treatments to teeth or dental trauma cause dental discoloration.
Does Teeth Whitening Affect the Enamel?
Accredited substances used today (carbamide and hydrogen peroxide) do not cause damage to the dental structure, as long as they are used with discernment, as recommended by the dentist.
Do Teeth Bleach Every Time?
Peroxides cannot whiten the tooth when dealing with hematologic, hepatic or dental fluorosis because in these cases the color appears from inside the teeth.
Contraindications. Tooth whitening is not recommended in these cases:
1. Pregnant or breastfeeding women.
2. Children under the age of 16, as their dental pulp is still in development.
3. Patients with multiple caries lesions. That can whiten their teeth after all injuries are treated.
4. People allergic to substances used in whitening or those who generally suffer from dental sensitivity or exposed dental roots (areas where the protection of dental enamel is absent).
When Do We Whiten Our Teeth Again?
The whitening procedure can be resumed without risk after 2 or 3 years.
Hygiene After Whitening
Dental hygiene is important after whitening for the whitening effect to last longer. It is advisable to visit your dentist at least 6 months for professional teeth cleaning.
Teeth whitening can make your teeth look much better but there are many factors to take into consideration before and after you have the procedure. Additionally, the procedure is not for everyone so make sure you talk to your Dentist before getting it done.
