A dental filling treats a cavity by removing decay and filling the space with a tooth-colored material that restores the tooth's strength and shape. It's a quick, routine treatment, often done in a single visit, that stops decay from spreading and helps you avoid bigger problems down the road.
A filling repairs a tooth that's been damaged by decay. We gently remove the decayed part of the tooth, clean the area, and fill it with a durable, tooth-colored composite that blends in with your natural smile. The material restores the tooth's shape, strength, and function.
We use natural-looking, mercury-free composite fillings, so your repair is discreet and your tooth looks like itself again. Most fillings are completed comfortably in a single visit.
Fillings work best for small to moderate cavities. If a tooth has more extensive damage, we'll talk through stronger options like an inlay, onlay, or crown, and we'll always explain what we recommend and why.
You may need a filling if you:
Note: Sometimes early decay has no symptoms at all, which is exactly why regular exams matter. We catch and treat cavities while they're still small.
Common signs include:
A toothache or sensitivity to hot, cold, or sweet foods
A visible hole, pit, or dark spot on a tooth
A rough or chipped edge you can feel
Food repeatedly getting stuck in one spot
A lost or cracked old filling
Our practice is on the 18th floor at 8 S Michigan Ave, steps from Millennium Park and the heart of the Loop. Because most fillings are done in one visit, treatment is easy to fit into a busy downtown day.
We welcome patients from across downtown Chicago, including the Loop, River North, South Loop, and West Loop, with convenient access by CTA, Metra at Millennium Station, and nearby parking.

The cost of a filling depends on the size and location of the cavity. Fillings are restorative care, and dental insurance often covers a good portion of them. We're in-network with most major PPOs and will review your benefits with you before treatment.
To keep things easy, we offer financing through CareCredit and Cherry, and members of our in-house membership plan receive 15% off treatments like fillings. We'll always give you a clear estimate up front.
Fillings are safe and routine, but a few things are worth knowing. It's normal to feel some temporary sensitivity for a short time after a filling, which usually fades quickly. Fillings also don't last forever, so over the years a filling may need to be replaced.
A filling also isn't always the right tool. If a cavity is large or the tooth is significantly weakened, an inlay, onlay, or crown may protect the tooth better. If decay has reached the nerve, more advanced treatment may be needed, and we'll discuss your options and coordinate a trusted referral when appropriate. Treating decay early almost always means a simpler, smaller repair.
No one loves hearing they have a cavity, so we make treatment as easy and painless as possible. Our gentle, patient-first approach and natural-looking, tooth-colored fillings mean comfortable visits and repairs that blend right in.
As a woman-owned, family-friendly practice in the heart of the Loop, we pair modern dentistry with genuine, personal care, and a focus on preserving your natural teeth.

It depends on the size and location of the cavity. Fillings are restorative care and are often partially covered by dental insurance. We're in-network with most major PPOs, offer financing and a 15% member discount, and we'll give you a clear estimate before we begin.
For most people, no. We fully numb the area so you stay comfortable during treatment. Some mild sensitivity afterward is normal and usually fades within a few days.
With good care, fillings commonly last many years. Their lifespan depends on the size, location, and your habits, and we keep an eye on your fillings at every checkup so we can refresh one when needed.
A filling repairs a small to moderate cavity, while a crown covers and protects a tooth that's heavily decayed or weakened. An inlay or onlay sits in between. A filling is best for smaller damage; a crown is best when more of the tooth needs protection. We'll recommend what suits your tooth.
Tooth-colored composite fillings are natural-looking, bond to the tooth, and are mercury-free, which is why we use them. They blend in with your smile rather than showing a dark spot.
