Readers, if you have non-emergency questions, please post them under "Comments" at the bottom of this page. I will try my best to answer them.


Question: Why do I have tooth pain when bite on tin foil or metal 
spoons?
Answer: It is a galvanic reaction between 2 different metals. In this case, metal in an amalgam filling reacts with the foil or metal spoon generates mild currents flowing between tooth and tinfoil results in irritation to the nerve inside the tooth.

Occasionally,  patient with two difference metal fillings, e.g., gold in one tooth and amalgam filling in the opposing tooth when bringing them together also experiences a galvanic reaction.

Question: If the permanent crown came out, can I re-attach the crown with superglue?

Answer
: No. Here are the reasons:
  1. Superglue (cyanoacrylate) does not provide strong bond
  2. Superglue may compromise the margin of the crown
  3. When you re-attach the crown, you may not place it correctly in its place
  4. Health hazard
Question: Why I have a toothache during the flight?

Question: Why does my lower lip/tongue numb after dental procedure
that does not involve surgery?

 Answer: This condition is called "Paresthesia". Paresthesia, in this case, caused by an injury to the nerves to the lower lip and tongue during anesthetic injection. The recovering process may take up to six months depends on the level of severity of the injury.

Question: When I chew food or yawn, I hear a clicking sound.  What should I do?

Answer: You may need to have an occlusal adjustment. One of the most common causes is the loss of an occlusal guidance or uneven teeth due to malocclusion, grinding teeth at night, or accidentally chipped part of your tooth.  Consult with the dentist who used "computerized occlusal analysis" about re-establish the occlusal guidance and adjust your occlusion.

Question: I have few teeth left in my lower jaw, will it be better to remove all my teeth and have the dentures instead?

Answer: Only if the teeth have dental problems (severe gum disease, large cavity, or failed root canal treatment that can not be saved),  it is better to keep your teeth.  The dentist can use those few teeth to anchor a partial denture, especially in a lower jaw where the dental arch is narrow created less support to the denture.

Question: What keep dentures stay in place without dental adhesive?

Answer:
Dentures remain in place by suction with an excellent seal around the denture border in a wet environment.  The denture has a better seal with large surface coverage that is the reason an upper denture tends to remain in place better than a lower denture.  Once the seal breaks, the denture dislodge.
