When a dental filling falls out after treatment, it can be concerning and may lead to further complications if not addressed promptly. In your case, it seems that the filling you received after experiencing a crack and a small surface defect has come loose, possibly due to a combination of factors related to the filling material, your oral habits, and the condition of the tooth itself.

Firstly, it is important to understand that dental fillings, especially those made from composite resin (often referred to as "tooth-colored" fillings), can be sensitive to various factors. These include the way the filling was placed, the condition of the tooth before the filling, and how you care for your teeth afterward. If the filling was not adequately bonded to the tooth structure or if there was any moisture during the placement, it could lead to a weak bond, making the filling more susceptible to falling out.

In your situation, you mentioned that you have been licking the area where the filling was placed. This behavior can introduce additional moisture and bacteria to the site, which may weaken the bond of the filling. It is advisable to avoid touching or licking the newly filled area until it has fully set and your dentist has confirmed its stability.
Regarding the dentist's decision to smooth out the tooth before placing the filling, this is a common practice. Smoothing the surface can help ensure a better fit for the filling and reduce the risk of future complications. However, if excessive tooth structure is removed during this process, it can lead to a shorter tooth over time. It is crucial to communicate your concerns with your dentist, as they can provide you with a clear understanding of how much tooth structure was removed and what to expect in terms of longevity and function.

If you return to your dentist for a replacement filling, they may need to smooth the tooth again to ensure a proper fit for the new filling. While this is a standard procedure, it is essential to discuss your worries about the tooth becoming shorter. Your dentist can assess the situation and determine the best course of action to preserve as much tooth structure as possible while ensuring the filling is secure.

As for the filling in the interproximal area (the space between your teeth), these areas can be more challenging to fill and may be more prone to falling out if not done correctly. Proper technique and the right materials are crucial for ensuring that these fillings remain intact. Regular brushing and flossing are essential to maintain oral hygiene and prevent decay around the filling, but be gentle around the filled area to avoid dislodging it.

In summary, if your filling has fallen out, it is essential to schedule a follow-up appointment with your dentist as soon as possible. They can assess the situation, replace the filling, and address any concerns you have about the integrity of your tooth. Maintaining good oral hygiene and avoiding habits that may compromise the filling will help ensure its longevity. Always communicate openly with your dentist about your concerns, as they can provide tailored advice and treatment options based on your specific situation.
