Contact your dentist to bleach the seal. The doctor will remove the layer of old material and impose a new one. The procedure is completely painless, so do not be afraid to go to the dentist. If you have a desire, then the specialist will make a bleaching and dentition, in this case, grind the seal, most likely, do not have to.
If you are afraid of people wearing white coats and do not want to go to the hospital for such a trifle, try to whiten your teeth with improvised means. Buy a quality whitening toothpaste with abrasive particles and a stiff brush. Brush your teeth several times a day. If the filling is badly bleached, apply a toothpaste on it and wait 10 minutes, then brush it.
For lemon bleaching, lemon juice is also suitable. Dampen the fleece in it and put on the seal for 10-15 minutes. The procedure is carried out several times a day to achieve the best result. Instead of lemon juice, hydrogen peroxide with a small addition of ammonia is also suitable. The composition is nontoxic, but still it is best not to take it inside.
You can bleach the seal with soda. Dampen the toothbrush and soak it in soda. Thoroughly clean the sealed tooth. Gradually the seal will become more white.
The chewing gum has a light whitening effect. If you have a strong seal, then several times a day, clean the dental arch with it. But be careful, the seal can fly out and you have to go to the dentist.
When bleaching fillings, try to be very careful. If nothing happens to the artificial material, the enamel of the teeth may suffer because of the mechanical action of the abrasive particles. It is better to consult a specialist if you have problems with the gums or there is an increased sensitivity of the teeth.
