A deep cavity represents a more advanced stage of tooth decay, where bacteria have penetrated beyond the outer layers of enamel and deeper into the dentin, approaching the pulp (nerve). This condition is often accompanied by a dull, lingering toothache, especially when exposed to hot, cold, or sweet foods.
If not treated promptly, the inflammation can reach the dental nerve, leading to pulpitis – a painful condition that requires more complex and invasive treatment, such as root canal therapy.
The treatment of a deep cavity is more delicate and may take longer. After applying local anesthesia to ensure a painless experience, the dentist carefully removes the decayed tissue. The cavity is then disinfected with antiseptic solutions to eliminate bacteria and prevent further infection.
In some cases, when the decay is close to the nerve, a special protective base material is applied to shield the pulp and support natural tissue regeneration.
The cavity is then restored using a strong composite filling, precisely shaped and polished to ensure a smooth bite and natural feel.
After treatment, the tooth may remain sensitive to temperature changes or pressure for a few days, but this sensitivity usually subsides on its own.
