Suggest Treatment For Chronic Canker Sores
Investigation
Detailed Answer:
Hi,
You seem to have bad canker sores. We call them Aphthous stomatitis.
If the dentist had referred back to family physician then what he means is that there is no dental cause involved in your case. Having said you should be investigated thoroughly further. There are multiple other reasons why recurrent canker sores occur in humans. E.g Iron deficiency, HIV or Behcet disease, Coeliac disease, GERD, simple vitamin deficiency as well. So it means the physician has to investigate with battery of tests ( serum iron/folate/vitamin B12 levels) to rule these conditions. Since these are recurrent, you should meet a oral pathologist for an biopsy of the ulcer to determine the nature of it.
Till then I suggest you to use ORABASE gel over the ulcers before every meal. Pharmacy can give you Lidocaine gel or Benzydamine gel to help with pain due to sores.
Do Chlorhexidine mouth washes thrice a day to prevent infections.
If nothing helps steroid injections would definitely help.
