Hello,

Thanks for consulting HCM

Read your query yes these symptoms are of pericoronitis dont worry for swollen cheek and reduced mouth opening you do warm saline rinses two - three times a day, and take drug like flexon MR by consulting with you local doctor .
I will also suggest you to consult oral surgeon and go for curretage of infected partially erupted tooth and iopa xray of wisdom tooth to know the orientation of wisdom tooth.

Hope this will help you.
Wishing you good health.

Regards,
Dr. Priyanka tiwari

Thanks for using Health Care Magic.

Read your query.

Erupting third molar usually presents with pain , swelling and difficulty in mouth opening .

For the pain , ibuprofen can be taken (if you are not allergic to any medicine).
Do salt water gargling and avoid application of hot bag externally.

I would advice you to visit a oral surgeon and have it evaluated. Radiograph will help to know the exact position of the erupting tooth. If impacted , extraction is adviced.Antibiotics like amoxicillin and metrolag on prescription will be needed.

Hope this was useful.
Thanks and regards .
