Over-the-counter products exist to provide temporary filling for cavities or minor tooth damage until you can visit the dentist, but it’s important to note that they are not a permanent solution and cannot substitute a professional filling. Cavities represent permanent tooth damage that requires proper cleaning, preparation, and filling by a dental professional. Allowing dental decay to progress without treatment poses severe risks. Untreated cavities can lead to tooth loss and potentially result in a tooth abscess. Seeking timely professional dental care is crucial to prevent further complications and maintain oral health.
