Have you just discovered or been told you have a dental cavity (or two)? It’s likely that you’ll need fillings to restore your smile and oral health.
However, there’s bound to be some uncertainty on your part.
- Will it hurt?
- What will my Chandler dentist use?
- Most importantly, how long will the procedure take?
If you’ve been putting off getting a cavity filled because you’re not sure what to expect, you’re not alone. Most people just want to know one thing: how much of your day will it actually take?
The short answer is usually under an hour. The longer answer depends on a few factors worth understanding before you sit in the chair.
Read on to get a better idea of what goes into the tooth filling process.
What’s Actually Happening Inside a Cavity
Cavities are often the result of unchecked tooth decay.
Decay starts when bacteria in your mouth produce acid that gradually wears down enamel, the hard outer layer of your tooth. Over time, that erosion creates a small hole.
Left alone, bacteria continue working deeper into the softer structure underneath, eventually reaching the root and nerve. When this happens, damage to the tooth enamel and underlying nerves can get significantly more complicated and expensive.
For this reason, you need to come in for a dental exam to check the severity of tooth decay. By getting a filling while the decay is still shallow, your procedure and recovery can be faster, simpler, and less expensive.
So, How Long Does It Take?
For most straightforward cases, you’re looking at 30 to 60 minutes from numbing to walking out the door.
A small cavity on an easy-to-access surface of a molar lands closer to the 30-minute mark. One that’s formed between two teeth, or has progressed deeper into the enamel, can run the full hour. If multiple cavities are addressed in one visit, plan for additional time per site.
In any case, we’ll give you a realistic time estimate at your appointment once we’ve assessed the extent of decay with X-rays.
What Happens During the Appointment
There’s no mystery to it. Here’s how a filling appointment actually flows:
- Numbing the area: Before anything else, we apply a topical gel to the gum around the site, then follow with a local anesthetic injection. Most people feel light pressure at most. We wait until the area is fully numb before moving forward.
- Removing the decay: Using a small drill or laser, we clear out the damaged material and clean the area. How long this takes depends directly on how much decay is present.
- Placing the filling: Once the cavity is clean, we fill it with your chosen material, shape it to match the natural contour of your bite, and cure it. We’ll cover material options below.
- Checking the bite: Before you leave, we have you bite down on a thin paper to check alignment. If anything feels off, we adjust on the spot. You should leave feeling like nothing is there.
Filling Materials and How Long They Take To Set
The material used affects both how the filling looks and how quickly it hardens after placement.
Composite Resin
This is the most common choice today. It’s tooth-colored, bonds directly to the existing structure, and hardens almost instantly under a curing light — layer by layer in roughly 3 to 20 seconds each. You can eat normally as soon as the numbness wears off.
Ceramic (Porcelain)
Ceramic fillings are also cured with light and set immediately. They’re highly durable and blend seamlessly with surrounding enamel, making them a strong option for visible areas.
Amalgam (Metal)
These fillings are less common now but still used in some cases. They take about an hour to reach initial hardness and up to 24 hours to fully set.
You’ll want to avoid chewing hard or sticky food on that side for at least a day.
Glass Ionomer
This filling material is a tooth-colored cement-based option that begins hardening within about five minutes but continues strengthening over several days. It’s often used for cavities near the gumline or in lower-pressure areas.
FAQs
Can I Eat Right After?
With composite or ceramic fillings, yes — once the anesthetic wears off, typically within two to three hours. With amalgam, hold off on anything tough or chewy for 24 hours. Regardless of material, waiting for the numbness to fully clear before eating reduces the risk of accidentally biting your cheek or tongue.
Will It Hurt?
The injection can produce a brief pinch, but the procedure itself should be painless. Some sensitivity around the filled area is normal for a few days afterward, especially to hot or cold. If sensitivity lingers beyond a week, let us know.
How Long Will the Filling Last?
Composite fillings typically last seven to 10 years with proper care. Ceramic and amalgam can last longer. Consistent brushing, flossing, and keeping up with regular checkups are the main factors in longevity.
How Long Will My Mouth Stay Numb?
Local anesthetic usually wears off within two to four hours, though some people notice residual effects for up to eight hours. Avoid chewing until you have full sensation back.
