Hi Prabir, sorry to hear, that you problem in opening your mouth.
As you told wisdom tooth is erupting. Quite possibly this problem is related to this erupting tooth.It is quite possible, that there infectio around you wisdom tooth which has spread to other parts, thus making the muscles which open our mouth. I advise to get the tooth extracted, by an Oral Surgeon (specialist in controlling the infection
and extracting teeth) best solution. Or in case, you don't want extraction, go and see a A Periodontist
, as they can treat your condition in best way possible.
If you want me to suggest a good Oral Surgeon or Periodontist, message your city and locality. If having pain
you can take Orthodex
- MR, it's brand that is available with most of the chemists. If not then you can ask for a pain killer with muscle relaxant. Don't take any Medicine whatsoever, unless prescribed by the doctor.
But do see to the Doctor immediately. It can become life threatening, although till this time it is completely curable.
Get well soon and God Bless.
