When it comes to diagnosing secondary cavities, also known as recurrent caries, there are several signs and symptoms to be aware of. Secondary cavities typically occur around existing dental restorations, such as fillings or crowns, and can be a significant concern for dental health.
In your case, the discomfort you experience when using dental floss on the tooth that has been previously restored could indeed indicate the presence of secondary caries. Here are some key points to consider regarding the signs and symptoms of secondary cavities:
1. Sensitivity or Pain: As you mentioned, experiencing sensitivity or pain when pressure is applied to the restored tooth can be a sign of secondary decay. This sensitivity may be triggered by hot, cold, or sweet stimuli, or even by mechanical pressure from flossing or chewing.

2. Visual Changes: Dentists often look for visual signs of decay during examinations. This can include discoloration around the edges of the filling, which may appear darker or have a different texture compared to the surrounding tooth structure. If you notice any changes in the color or texture of your filling or the tooth itself, it’s worth mentioning to your dentist.

3. Bad Breath or Unpleasant Taste: The presence of decay can sometimes lead to an accumulation of bacteria, which may result in bad breath or an unpleasant taste in the mouth. If you notice these symptoms, they could be indicative of underlying issues.

4. Swelling or Gum Issues: If the area around the restored tooth becomes swollen or if you notice any gum issues, such as bleeding or tenderness, these could be signs of infection or decay that needs to be addressed.

5. X-ray Findings: The most definitive way to diagnose secondary cavities is through dental X-rays. These images can reveal decay that is not visible to the naked eye, particularly around the margins of fillings. If your dentist suspects secondary caries, they may recommend taking X-rays to assess the situation.

6. Changes in Bite or Alignment: If you notice that your bite feels off or if you experience discomfort when chewing, this could also indicate that something is wrong with the restored tooth or surrounding teeth.

Given your symptoms, it is advisable to schedule an appointment with your dentist for a thorough examination. They can assess the condition of the filling and the surrounding tooth structure, possibly using X-rays to determine if there is indeed secondary decay present. Early detection and treatment are crucial in preventing further decay and potential complications, such as the need for more extensive dental work or even tooth extraction.

In summary, while your symptoms may suggest the possibility of secondary cavities, only a dental professional can provide a definitive diagnosis. It’s important to address any discomfort or changes in your dental health promptly to maintain optimal oral health.
