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.

Dr. John Ku will examine your teeth and take digital X-rays to determine the extent of any decay.
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.
