Treatment modalities advised.
Hello and welcome.
Thanks for sharing your concern.
After going through the history posted here I can suggest you following two treatment modalities.you can choose based upon your convenience.
1.If the cavity appears very small radio graphically and the wisdom teeth is fully erupted in your mouth,then it is better to go for filling or restoration.
2.But, In case your dentist
says, that the cavity is inaccessible and it might cause problem later,then in that case please go for extraction of wisdom tooth and restoration of adjacent tooth.This will permanently solve the problem,in case of small cavities.
Hope it helps.
Please let me know for further doubts.
