Tooth Decay and Cavity Treatment in Woodinville, WA
Tooth decay is one of the most common health conditions in the world, affecting children and adults alike. Left untreated, a small cavity can grow into a painful infection that threatens the entire tooth. At Oasis Family Dentistry, Dr. Tim Hung detects decay early with digital imaging and treats it with conservative, natural-looking restorations that protect your smile for years to come.
Request an AppointmentWhat Causes Tooth Decay?
Your mouth is home to bacteria that feed on sugars and starches from the foods and drinks you consume. As they feed, these bacteria produce acids that attack tooth enamel. Over time, repeated acid attacks weaken and dissolve the enamel, creating small holes called cavities. If decay continues, it can reach the softer dentin layer and eventually the nerve at the center of the tooth.
Several factors increase your risk of developing cavities:
- Frequent snacking or sipping sugary and acidic drinks such as soda, juice, and sports drinks
- Inconsistent brushing and flossing that allows plaque to build up
- Dry mouth caused by medications, medical conditions, or mouth breathing
- Deep grooves in molars that trap food and bacteria
- Receding gums that expose vulnerable root surfaces
- Skipping regular dental cleanings and exams
Signs and Symptoms of Cavities
Early decay often causes no symptoms at all, which is why routine checkups are so important. As a cavity grows, you may notice:
- Sensitivity to sweets, hot, or cold
- A toothache or sharp pain when biting
- Visible holes, pits, or dark spots on a tooth
- White, brown, or black staining on the tooth surface
- Food frequently getting stuck in one area
How We Diagnose Tooth Decay
Dr. Hung combines a careful visual exam with low-radiation digital X-rays, which reveal decay between teeth and beneath old fillings. Our intraoral camera lets you see magnified images of your teeth on screen, so you understand exactly what’s happening and why treatment is recommended.
Treatment Options for Cavities
The right treatment depends on how far decay has progressed:
- Early enamel weakening: Professional fluoride treatments can help remineralize enamel and reverse the earliest stages of decay.
- Small to moderate cavities: Tooth-colored dental fillings remove decay and restore the tooth with a natural look.
- Large cavities: A custom dental crown covers and strengthens a tooth weakened by extensive decay.
- Decay reaching the nerve: Root canal therapy removes infected tissue and saves the natural tooth.
- Non-restorable teeth: When a tooth can’t be saved, a gentle extraction followed by a dental implant or bridge restores function.
Preventing Tooth Decay for the Whole Family
Prevention is always easier than treatment. Brush twice daily with fluoride toothpaste, floss every day, limit sugary snacks between meals, and drink plenty of water. For children and teens, dental sealants provide a protective barrier over the chewing surfaces of molars, where most childhood cavities begin.

Frequently Asked Questions About Tooth Decay
Can a cavity heal on its own?
Very early enamel weakening can sometimes be reversed with fluoride and good oral hygiene. Once a true cavity forms, however, the damage is permanent and requires a filling or other restoration from your dentist.
How do I know if I have a cavity?
Early cavities often have no symptoms. As decay progresses, you may notice sensitivity, pain when biting, or visible dark spots. Regular checkups with digital X-rays are the most reliable way to find cavities early.
Do fillings hurt?
Fillings are performed with local anesthesia, so most patients feel only mild pressure. For anxious patients, we also offer nitrous oxide.
What happens if tooth decay is not treated?
Untreated decay can spread to the inner pulp, causing infection, abscess, and severe pain. It may eventually lead to tooth loss and require root canal therapy or extraction.
Are children more prone to cavities?
Children are at higher risk because they are still developing brushing habits and often snack frequently. Sealants, fluoride, and regular visits greatly reduce their risk.
Do you use tooth-colored fillings?
Yes. Oasis Family Dentistry uses tooth-colored composite fillings that blend naturally with your smile and bond directly to the tooth.
How often should I visit the dentist to prevent cavities?
Most patients should visit every six months. If you are at higher risk, Dr. Hung may recommend more frequent visits or additional preventive treatments.
