The signature symptoms are the appearance of pain, pits, cracks, and cavities, which are small and barely noticeable in the beginning, sensitivity to cold, hot, sweet foods and drinks. The symptoms depend on the depth of the dental decay. If it is an initial caries, that is located in the enamel, the chances are that it won’t show any significant symptoms. During this time, the dentist is the only one that can discover the cavity during a regular checkup. Once the caries reaches the dentin, that is when the symptoms appear. All of the nerve endings are located there, so that is why the patient starts feeling pain. That pain is usually very sharp and when the patient drinks or eats cold drinks and food. Foods that contain sugar can also trigger pain. You will see a cavity, that can be colored in either yellow, brownish to even black, depending on the size and the time. At a certain point there will be visible holes in the teeth. If the caries progresses it can affect the dental pulp. The pain will lead to difficulty in eating, bad oral hygiene at that part of the mouth, the caries can even affect surrounding teeth and compromise your hole oral health.
