Hopefully the nightguard helps with the sensitivity. The toothpaste should help as well. Yes, some people have thin gum biotype. Unfortunately that means your gums are very delicate. You just need to be more diligent about taking care of it. Let me know how things go.
Dr. Tsang,
Thanks for you response!! The periodontist said i have a thin gum biotype, but the pain I was experiencing was most likely from bruxism, as I showed no signs of gingivitis. I have been using crest sensitivity toothpaste and I am using the "doctors nightguard", OTC every night.
The nightguard should help with the bruxism and it should help to slow down the recession of the gums due to the trauma of bruxing. Did your dentist or periodontist have any recommendations to prevent the gum recession? As for the sensitivity, you may want to try some sensitivity toothpaste such as Sensodyne or Colgate Total and see if that helps you out. You can always go back to your dentist to see if he can apply some desensitizer such as MI Paste to see if that helps as well.
