Mild dental issues can be treated with home remedies or over-the-counter medications as you wait for your next dental appointment. However, severe dental problems require the immediate attention of an emergency dentist. For instance, a persistent toothache requires urgent dental care to determine the cause of the pain. Ignoring such an issue and failing to seek immediate professional help can worsen the problem. Therefore, you should visit your dentist as soon as you start experiencing a strange dental problem.
