The short answer
Decay on lower teeth is caused by acid from plaque bacteria and is treated according to whether the damage is early, cavitated, or has reached the pulp.
Where can cavities develop on lower teeth?
Lower teeth can develop caries on grooves, smooth surfaces, root surfaces, or between teeth. The visible spot does not reliably show depth because dentine or pulp may be affected underneath.
What examination is needed for lower tooth decay?
Arrange examination and radiographs when indicated. Early mineral loss may need fluoride and plaque control, a cavity may need a filling, and deeper disease may require pulp treatment and a restoration.
Which symptoms make lower tooth decay urgent?
Seek prompt care for spontaneous pain, lingering hot or cold pain, swelling, fever, a bad taste, or a broken tooth.
