A dental filling is a common restorative treatment used to repair teeth affected by decay, cavities, minor fractures, or wear. During treatment, the damaged portion of the tooth is removed and replaced with a durable filling material that restores the tooth's shape, function, and strength. At W Plus Dental, we use tooth-colored composite fillings that blend seamlessly with your natural teeth.

Many cavities develop without noticeable symptoms, which is why regular dental exams are so important. However, here are five common warning signs. If you're experiencing any of these symptoms, scheduling a dental exam can help prevent the problem from becoming more serious.
If you experience discomfort when eating hot, cold, or sweet foods, a cavity may be developing.
Pain or pressure when biting down may indicate decay or a damaged tooth.
Brown, black, or white spots on a tooth can be early signs of tooth decay.
Minor fractures and worn enamel can often be repaired with dental bonding or fillings.
A cavity can create areas where food becomes trapped between teeth.

The damaged portion of the tooth is carefully removed while preserving as much healthy tooth structure as possible.
A tooth-colored composite material is applied and bonded directly to the tooth.
The filling is adjusted to ensure a comfortable bite and polished to create a natural appearance.
Most filling appointments take less than an hour, and patients can typically return to normal activities the same day.
A cavity will not heal on its own. Without treatment, decay continues to spread deeper into the tooth.
Early treatment with a filling can help prevent:
✔️ Severe toothaches
✔️ Dental infections
✔️ Root canal treatment
✔️ Dental crowns
✔️ Tooth extractions
✔️ Dental implants
The sooner a cavity is treated, the more conservative and affordable treatment tends to be.
