Thanks for asking the query,
Wisdom tooth are often tilted in position and impacted in the jaw bone which leads to pain .
The area is often difficult to clean so it often invites bacterial infection leading to redness
, inflammation and swelling of the overlying gums known as pericoronitis
You get a checkup done by Oral Surgeon , take an OPG x-ray ,
Depending upon which treatment will be decided.
Antibiotic and analgesic
will give temporary relief.
You either have to go for treatment of pericoronitis by raising flap and creating room for eruption of tooth , or extraction of the wisdom tooth, as this tooth does not have any significant role in mastication and occlussion .
Use lukewarm saline gargles 3-4 times a day.
Use antiseptic mouthwash gargles twice daily .
Avoid eating hot and spicy food , eat soft diet.
Maintain a good oral hygiene .
Hope this helps out.
