Hello! Thank you for your detailed questions regarding dental resin loss and related concerns. Let's address each of your queries systematically.

1. Why do dental fillings fall out?
Dental fillings can fall out for several reasons. One common reason is recurrent decay underneath the filling, which can weaken the bond between the filling material and the tooth structure. Over time, fillings can also wear down due to normal chewing forces, especially if they are made from materials that are not as durable. If a filling has been in place for many years, it may simply reach the end of its lifespan and need replacement. Regular dental check-ups can help identify potential issues before they lead to filling loss.

2. Is it normal to feel sensitivity in the cavity when drinking cold water?
Yes, experiencing sensitivity or a sharp pain when consuming cold beverages can be a sign that the tooth is compromised. This sensitivity often indicates that the nerve inside the tooth may be irritated or that there is decay present. If the filling has fallen out, the exposed dentin (the layer beneath the enamel) can react to temperature changes, leading to discomfort. It's important to see a dentist promptly to address this issue.

3. Can X-rays determine if decay has reached the nerve?
X-rays are a valuable diagnostic tool, but they have limitations. While they can show the presence of decay and the extent of it, they may not always reveal whether the decay has reached the nerve or pulp of the tooth. Dentists often rely on clinical examination and patient symptoms in conjunction with X-ray findings. If a dentist suggests drilling to assess the extent of decay, it is typically to ensure that all decay is removed and to prevent further complications. If you have concerns about a dentist's recommendations, it is perfectly acceptable to seek a second opinion.

4. Can decay occur under resin fillings?
Yes, decay can still occur under resin fillings if the filling was not placed properly or if there was pre-existing decay that was not completely removed before the filling was placed. Additionally, if oral hygiene is not maintained, bacteria can accumulate around the edges of the filling, leading to new decay. It’s great to hear that you are diligent with your oral hygiene, as this significantly helps in preventing further decay.

5. When is a crown necessary?
Crowns are typically recommended when a tooth has extensive decay that cannot be adequately restored with a filling, or when a tooth has undergone root canal treatment. A crown helps to protect the tooth and restore its function. If a tooth is structurally compromised, a dentist may suggest a crown to prevent further damage.
Regarding your concerns about finding a trustworthy dentist in the Taoyuan area, it’s essential to seek recommendations from friends or family, or check online reviews. A good dentist should prioritize your health and provide clear explanations for any recommended treatments. Don't hesitate to ask questions about the necessity of procedures and the costs involved.

In summary, maintaining regular dental visits and being proactive about any changes in your oral health is crucial. If you feel uncertain about a treatment plan, seeking a second opinion can provide peace of mind and ensure you receive the best care possible. Thank you for your questions, and I hope this information helps you navigate your dental health concerns!
