Hello
i read your problem.it seem you have stiff muscles
due to which you are not able to open your mouth
Wide.its nothin wrong in it.since thete is no pain
swellin or inflammation there is no reason to worry.
Inflammation around wisdom tooth is because it may be impacted
And infected.since wisdom tooth does not carry any function
in our mouth its an extra tooth and since in your case its
getting infected i would also advice you to extract it.
You can increase your mouth opening by doing an excercise
of slowly opening your mouth twice daily .you may even
try keepin a small stick in between yoir upper and lower teeth
that will hold your mouth open.

Hi,
Thanks for posting your query.

First, there are certain reasons for reduced mouth opening:
-muscle contraction: it can happen due to infected wisdom teeth, trauma, impacted wisdom teeth, injury to the jaw or teeth, bruxism(severe clenching), TMJoint problems.
-OSMF-a condition due to beetle nut chewing. the tissue in cheeks ad around the oral cavity feels thick and fibrous.

Skin in front of your wisdom tooth is the flap which gets infected. Once you get the tooth removed that will get resolved on its own as food will not get lodged.

I would advice you to determine the cause of your problem discussing your habits or any medical/dental history with your doctor along with Xrays of the Jaw. Meanwhile you may start with warm saline garglea nad physiotherap, muscle relaxant(if prescribed by your doctor).

Hope you feel better soon.
Regards

Hello,
Thanks for posting your query,
I would like to inform you that extraction is the only treatment for an impacted wisdom tooth,
In your case, it is associated with symptoms like pain, therefore a thorough dental check up is needed prior to extracting it.
Impacted tooth is generally caused by more tooth- less bone ratio, where the the third molar does not have space to be erupted in the occlusion.
The most common cause of pain from impacted tooth is the inflammation in the soft tissue covering over the offending tooth(Pericoronitis), mostly caused by food impaction in the soft tissue space over the tooth and/or bite injury over the soft tissue covering the impacted tooth, by upper molar tooth.
Also, in order to relieve symptoms like pain and swelling,your dentist will prescribe antibiotics and anti-inflammatory medication if needed.
I hope this information has been both informative and helpful
