A throbbing toothache, one that pulses in time with your heartbeat, usually means the nerve inside the tooth is inflamed or infected. Pressure builds inside the tooth and there is nowhere for it to go.
Common causes include deep decay, a cracked tooth, a large or broken filling, or a dental abscess. Pain that comes on by itself, keeps you awake, or lingers long after hot or cold drinks is more likely to need treatment than a quick, sharp twinge.
Until you speak to a dentist: take pain relief that is safe for you, exactly as directed on the packet. Rest with your head raised, rinse with warm salty water, and avoid very hot, cold or sugary food and drink. Do not put tablets directly on the gum.

Book a video consultationAntibiotics do not usually help an inflamed nerve on their own. A dentist will work out the likely cause, advise on the right pain relief, prescribe if it is clinically appropriate, and tell you how soon the tooth needs treatment in person.
Go to A&E or call 999 if swelling spreads to your eye or neck, or you have difficulty breathing, swallowing or opening your mouth.
