If you have an upcoming filling appointment, you might feel a little nervous about what to expect. Understanding what happens during a dental filling — step by step — can make a huge difference in your comfort level. At Mertz Family Dentistry in Longmont, CO, Dr. Peter Mertz and his team walk every patient through the process before it begins. This guide covers exactly what happens, what you will feel, and how we keep you comfortable from start to finish.

Step One: Examining and Preparing the Tooth

Your appointment begins with a thorough exam of the affected tooth. Dr. Mertz uses Smile Gallery Longmont-quality precision tools and digital X-rays to confirm the extent of the decay. Digital X-rays give a clear, detailed image without unnecessary radiation exposure. This step ensures the treatment plan is accurate before anything else begins.

Once the tooth is evaluated, the area around it is cleaned and prepared. Dr. Mertz will dry the surrounding tissue to keep the workspace clean. This preparation phase is quick and entirely painless. It sets the stage for a smooth, efficient procedure.

Step Two: Numbing the Area with Local Anesthetic

Before any drilling begins, Dr. Mertz numbs the area completely. A small topical gel is applied to the gum first. This desensitizes the tissue so you barely feel the injection. Most patients are pleasantly surprised by how gentle this step feels.

Once the local anesthetic takes effect, you will feel pressure but not pain. Dr. Mertz always waits until the area is fully numb before proceeding. He checks in with you to make sure you are comfortable. Your comfort is the team’s top priority throughout every stage.

  • Topical gel is applied to the gum before the injection
  • A small amount of local anesthetic is administered
  • The tooth and surrounding tissue become fully numb
  • Dr. Mertz confirms numbness before moving forward

Step Three: Removing Decay and Shaping the Tooth

With the area numb, Dr. Mertz carefully removes all decayed tooth material. A dental drill or laser is used to clear out the damaged area. This step is precise — only the unhealthy portion of the tooth is removed. Healthy tooth structure is always preserved as much as possible.

After the decay is removed, the cavity is shaped to hold the filling securely. Dr. Mertz cleans the area thoroughly to remove any remaining bacteria. This cleaning step is critical for preventing future decay beneath the filling. The tooth is now ready for the filling material to be placed.

Patients often ask if this step hurts. Because the area is fully numb, most patients feel only mild vibration or pressure. If at any point you feel discomfort, simply raise your hand. Dr. Mertz and his team will pause immediately to address your comfort.

Step Four: Placing and Shaping the Filling Material

The most common filling material used today is tooth-colored composite resin. This material blends naturally with your existing tooth color. It is applied in thin layers and hardened with a special curing light after each layer. This layering process creates a strong, durable bond with the tooth.

Once the filling is built up to the correct size, Dr. Mertz shapes and polishes it carefully. He checks your bite to make sure everything feels balanced. Small adjustments are made until the filling sits perfectly. The result is a restoration that looks and functions like your natural tooth.

  • Composite resin is matched to your natural tooth color
  • Material is applied in layers and hardened with a curing light
  • The filling is shaped to match your natural bite
  • Final polishing creates a smooth, comfortable finish
  • Dr. Mertz checks your bite before concluding the procedure

What to Expect After Your Filling in Longmont

Once the procedure is complete, your mouth will remain numb for one to three hours. Avoid eating on the treated side until the numbness fully wears off. This prevents accidental biting of the cheek or tongue. It also keeps pressure off the newly placed filling while it fully sets.

Some mild sensitivity is normal for the first few days after a filling. You may notice slight discomfort when drinking cold or hot beverages. This typically resolves on its own within a week. If sensitivity continues beyond two weeks, contact Dr. Mertz for a follow-up evaluation.

Good oral hygiene is especially important after a filling. Brush gently twice a day and floss daily around the restored tooth. Regular dental checkups help Dr. Mertz monitor the filling over time. With proper care, composite fillings can last many years before needing replacement.

Frequently Asked Questions

Does getting a dental filling hurt?

Most patients experience little to no pain during a filling. Dr. Mertz numbs the area thoroughly with local anesthetic before beginning. You may feel pressure or mild vibration, but sharp pain should not occur. If you feel discomfort at any point, alert the team immediately and they will pause.

How long does a dental filling appointment take?

Most filling appointments take between 30 and 60 minutes. The exact time depends on the size and location of the cavity. Larger cavities or multiple fillings in one visit may take longer. Dr. Mertz will give you an estimated timeframe when you schedule your appointment.

How long do dental fillings last?

Composite resin fillings typically last seven to ten years or longer with proper care. Regular brushing, flossing, and dental checkups help extend the life of your filling. Avoid biting hard objects like ice or pens, which can crack a filling. Dr. Mertz monitors fillings at each routine visit.

Is a dental filling the same as a root canal?

No, these are two different procedures. A filling treats decay that has not reached the inner pulp of the tooth. A root canal is needed when decay or infection has reached the tooth’s nerve. Dr. Mertz will recommend the appropriate treatment based on your X-rays and exam findings.

When should I call the dentist after getting a filling?

Contact Mertz Family Dentistry if you experience pain when biting, prolonged sensitivity beyond two weeks, or a visible crack in the filling. These signs may indicate the filling needs an adjustment. Early follow-up prevents small issues from becoming larger problems. Dr. Mertz is always available to address post-procedure concerns.
