Hey Nidhi,
Clove oil or cloves are the most widely used and easily available home remedy for toothache. Clove oil contains eugenol which is a pain killer and has antibacterial properties. Small bottles of clove oil are available with most chemists and are also used by dentists for treatment. A small ball of cotton should be dipped in the clove oil and placed near the affected tooth. The pain will subside for some time. It is not advisable to go to sleep, using this pain relief method. Clove oil can cause a burning sensation in the mouth and can damage sensitive skin. People with diabetes and children should not use large quantities of clove oil, as it could be harmful for their health. Hope this tip would help your tooth ache.
