Although cosmetic dental fillings are increasingly improved with UV absorbers, anti-oxidants and therefore less discolored, tooth structure still endures a color change over time. 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. In this case, it is necessary to visit the dental office for cleaning and polishing.

2. Question: Why is the tooth sensitive after filling? What is the treatment?

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

  • Due to the pressure, the material is pressed into the sinuses when filling, causing dentin fluid to move in the dentinal tubules, causing 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.

Answer: When a hard object hits the tooth, although the tooth is not broken or chipped, it can crack 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 decomposition and bacteria, and H2S produces a reddish-brown or black compound. These substances seep into the teeth, causing them to become discolored.

4. Question: 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 covering part of the tooth surface with a composite layer of the same color as the tooth color.

Buy oral medication to relieve pain and swelling, stop taking pain medication and swelling recur. Ask: What are the long-term consequences? Is there any treatment without having to remove the old dentures?

Answer: As described, these two teeth did not receive root canal treatment or the treatment was unsatisfactory, leading to infectious complications, creating a pus-filled cavity in the apex of the tooth-bearing the denture. Although oral medications can stop swelling and pain for a while, this is highly undesirable for many reasons: the disease cannot be completely cured with medication alone, the disease will recur over and over again, and the pus pocket in the jaw bone will It grows larger and can damage nearby healthy teeth. Not to mention, self-medication (without a prescription) will lead to drug resistance, making it difficult to treat later, so it is advisable to visit a dental clinic for treatment as soon as possible.
