Author: Dr. Nhan Tam View: 654
Cosmetic fillings are a common dental treatment that does not cause you any discomfort. For small cavities, filling treatment can help prevent the development of cavities, so you should have a filling as soon as the decay has started or the cavity is small. Here are some answers and advice from Nhan Tam Dental Clinic about customers' questions about cosmetic dental fillings.

1. Will a cosmetic tooth be discolored after a period of filling? About how long after filling?

Answer: The color of a cosmetic filling or, in other words, a tooth-colored filling depends not only on the appropriate color selection from the beginning but also on the relative color changes that occur over time: both fillings and tooth structure can change color with age.

Although cosmetic fillings are increasingly improved with UV absorbers, anti-oxidants and therefore less discolored, tooth structure still endures a change in color over time. due to the darkening of ivory with age; Therefore, it is inevitable that the filling will change color inappropriately after many years.

In addition, it is necessary to distinguish true discoloration (as mentioned above) from discoloration caused by food, drink, or smoke. This case requires a visit to the dental office to clean and re-polish.

2. Why is a cosmetic dental filling sometimes sensitive after filling? tell me how to cure?

Answer: If you don't take into account the main pain caused by the pulp disease that should have been taken before filling, then a cosmetic dental filling that is sensitive after filling can be caused by the following reasons:

  • Due to the compressive pressure, the material is pressed into the sinuses when filling, causing dentin fluid to move in the dentinal tubules, creating pain.
  • Because when irradiating the lamp to harden the drug, the composite tends to shrink towards the lamp head, creating a gap at the interface between the composite and the dentin, then dentin fluid fills the gap. Therefore, when chewing, chewing pressure causes the liquid to move, creating pain.

In these cases, a doctor will need to re-examine the filling and may require re-filling.

3. The front teeth are injured by hard objects during sports, the teeth are discolored but not chipped. Could you please tell me the reason for the color change?

Answer: When a hard object hits the tooth, although the tooth is not broken or chipped, it can be cracked and the blood vessels that nourish the tooth (pulp) are broken causing bleeding and the release of iron-containing hemoglobin. Hemoglobin combines with NH3 from breakdown and bacteria, and H2S produces a reddish-brown or black compound. These substances seep into the teeth and cause the teeth to become discolored.

4. The upper front teeth are about 2mm wide, is there a way to naturally fit them without braces or dentures?

Answer: Currently, with the advancement of cosmetic dentistry, the case of sparse incisors can be closed by coating part of the tooth surface with a composite layer of the same color as the tooth color. This layer of medicine will stick to the teeth with special glue in dentistry. This technique gives good aesthetic results and is less expensive. But it should be noted that you should avoid eating and biting hard things on these teeth to keep the fillings strong.
