What Are Dental Fillings?
Dental fillings are performed by Dr. Qian at Mary Qian Dental Group.
Dental fillings are one of the most common and effective ways to restore a tooth that’s been damaged by decay, minor fractures, or everyday wear.
When a cavity forms or part of the tooth chips away, Dr. Qian gently removes the damaged area and fills the space with a durable material. This prevents the issue from progressing and restores both strength and appearance—so you can chew, speak, and smile with confidence.
As part of our restorative dentistry services in Palo Alto, we offer several types of fillings, including:
- Composite resin (tooth-colored and natural-looking)
- Porcelain (strong and aesthetic)
- Silver amalgam (durable but more visible)
- Gold (exceptionally long-lasting)
The right material depends on the size and location of the filling, as well as your personal preferences. Whatever the case, our team will help you choose the option that best supports your smile and long-term oral health.

Unlike your natural teeth,
dental implants can't get cavities.
Common Signs You May Need a Filling
Not all cavities cause pain right away—but catching them early can save you time, money, and discomfort. If you’re noticing any of the following symptoms, it may be time to visit your dentist:
- Tooth sensitivity to hot, cold, or sweet foods
- Visible holes, pits, or dark spots on a tooth
- Pain when chewing, brushing, or flossing
- A cavity that was previously monitored but has worsened
At Mary Qian Dental Group, we take a gentle, proactive approach to fillings—so you can get back to comfort and confidence quickly.
If you’re in Palo Alto and dealing with sudden pain or damage, you might need emergency dental care sooner rather than later. Call us—we’ll help you figure out what’s going on and what to do next.
Types of Filling Materials
At our Palo Alto dental office, we offer several types of filling materials to meet your needs.
Here’s a quick breakdown of the most common options:
Composite Resin (Tooth-Colored Fillings)
The most popular option for small to mid-sized cavities. Composite fillings are bonded directly to your tooth and can be color-matched to blend in seamlessly. Ideal for visible areas of the smile.
Porcelain Fillings (Inlays/Onlays)
Custom-made for strength and aesthetics, porcelain restorations are durable and highly stain-resistant. A great option for larger cavities where more support is needed.
Silver Amalgam
Made from a mixture of metals, amalgam fillings are very strong and cost-effective, though more noticeable than tooth-colored alternatives. Often used in back teeth that aren’t visible when you smile.
Gold Fillings
Gold is one of the longest-lasting materials available. Though less common today, some patients choose gold for its strength, durability, and biocompatibility.
Dr. Qian will recommend the best material for your tooth based on the size and location of the cavity, your preferences, and how much pressure the tooth typically handles.
No matter which option you choose, you can trust that your filling will be placed with precision, care, and lasting results.
What to Expect During a Filling Appointment
Getting a dental filling is a simple, comfortable process—and usually takes less than an hour. Here’s what to expect when you visit our Palo Alto office for treatment:
1. Numbing the Area
Dr. Qian begins by gently numbing the area around the affected tooth to keep you comfortable throughout the procedure.
2. Removing the Decay
Once the tooth is numb, she’ll carefully remove the decayed portion of your tooth using precise, traditional techniques.
3. Cleaning the Tooth
The space is then cleaned and prepped to ensure a strong bond with the filling material.
4. Placing the Filling
The chosen filling material—composite, porcelain, or another option—is placed in layers and shaped to match the natural contours of your tooth.
5. Bite Check and Polishing
Finally, Dr. Qian will check your bite, make any needed adjustments, and polish the filling so it feels smooth and natural.
Most patients return to their day right after their visit, with little to no downtime. You’ll leave with a stronger, healthier smile—and peace of mind.
Do Dental Fillings Hurt?
It’s one of the most common questions we hear—and the good news is, most patients say their filling appointment was far more comfortable than they expected.
Thanks to modern numbing techniques and Dr. Qian’s gentle, patient-first approach, you’ll feel little to no discomfort during the procedure. You may notice mild sensitivity for a day or two afterward, especially with hot or cold foods—but this usually fades quickly.
If you’ve had a filling in the past that now feels sensitive, cracked, or worn, it may be time for a replacement. Learn more about when dental fillings need to be replaced and how to tell if yours is still doing its job.

How Long Do Fillings Last?
Most fillings last anywhere from 5 to 15 years, depending on the material and how well you care for your teeth:
- Composite (tooth-colored): 5–10 years
- Silver amalgam: 10–15 years
- Porcelain or gold: 15+ years
Good brushing, flossing, and regular checkups can help your fillings last even longer. Dr. Qian checks them at every visit to catch signs of wear before they cause trouble.
Of course, the best way to prolong the lifespan of your fillings is to visit your dentist regularly for preventive care.

Frequently Asked Questions
Can you eat right after a filling?
If you received a composite (tooth-colored) filling, it hardens instantly, so you can eat right away—just avoid sticky or hard foods for the first few hours. If you have a silver filling, it’s best to wait at least 24 hours before chewing on that side.
Are silver fillings safe?
Yes, silver (amalgam) fillings have been used for decades and are considered safe by major dental associations. However, if you prefer a more natural look or have concerns, Dr. Qian can recommend tooth-colored alternatives.
Can cavities come back under fillings?
They can, especially if the filling becomes worn or if decay develops around its edges. That’s why it’s important to maintain good oral hygiene and come in for regular checkups—so we can monitor your fillings and catch any issues early.
Get ready for 5-star Experience
Dr. Qian is responsive, precise, and goes the extra mile to keep patients comfortable. I’ve had lots of dental work, and as a new patient in the past year, she guided me through the treatment of 2 complicated toothaches. On the lighter side, I was also very pleased with my teeth whitening procedure. Her staff is warm, helpful and professional.
