Hello. Since the tooth is paining already you cannot put a filling. Your tooth may require a root canal followed by a crown or an extraction ( if badly decayed). Consult your nearby dentist. He will check it clinically and take an x-ray. Accordingly he will write antibiotics and painkillers. Happy to help. Dr Zankhana Mody Mohile
