Hi mam greetings.
1-Kindly dont postpone the extraction of your 3 rd molar, because slowly it may lead to form an abscess.
2-after extraction also follow oral hygeine properly, since it is last tooth food deposits will easily accumulate there leading to delay in healing of socket.
Next Steps
First finish ur extraction, after proper healing go for fillings with each x ray (iopa or rvg), with glass ionomer cement,or a light cure composite, because always preventive measure is better than doing big treatment like root canal or extraction.
Health Tips
1-Do not keep clove or any other home remedies in the cavity or pain giving tooth area, it may increase the severity.
2-Don't take any painkilles or any self medication.
