Don’t ignore the warning signs

Cavities form when oral bacteria produce acids that erode your enamel and dentin. What begins as tiny holes can rapidly invade deeper structures, triggering a cascade of symptoms and serious complications:

Sharp or lingering pain, especially when eating or drinking anything sweet, hot, or cold
Increased sensitivity — a jolt when enjoying ice cream or sipping coffee
Visible pits or holes in the tooth surface
White, brown, or black spots marking early decay
Pain when biting down, signaling deeper damage
Persistent bad breath from bacterial overgrowth

Looking for a dentist who treats cavities in Eugene? Our team is here to diagnose and address decay with personalized care.

Why act early on tooth decay?

Early treatment often reverses decay, saving time, money, and discomfort.
Untreated cavities can cause abscesses, chewing problems, infection spread, and even life-threatening complications.
Protecting teeth avoids premature tooth loss and preserves your natural bite.

Our Treatment Strategy

In-Depth Examination – Dr. Sproul performs a thorough check-up using visual inspection, x-rays, and intra-oral scanning to detect decay early.
Minimally Invasive Care – We remove decayed areas while saving as much natural tooth structure as possible, and then use composite filling to seal the area.
Strengthening Teeth – We apply hydroxyapatite or fluoride to protect and fortify enamel.

Why we recommend hydroxyapatite

Hydroxyapatite (HAP) is a safe and effective way to strengthen your teeth, and it’s actually the same mineral your teeth are made of. While fluoride helps protect your enamel from acid, hydroxyapatite goes a step further by rebuilding and restoring weak spots in your teeth naturally.

It’s gentle, non-toxic, and even safe if swallowed, making it a great choice for kids, pregnant patients, or anyone looking for a fluoride alternative. Many of our patients also notice it helps reduce tooth sensitivity faster than fluoride.

Frequently Asked Questions

What causes cavities?

Cavities form when plaque bacteria feed on sugars and produce acids that break down your tooth enamel. Without regular brushing, flossing, and professional cleanings, small areas of decay can quickly get worse.

Can cavities be reversed if caught early?

Yes! In the early stages, before a full cavity forms, your enamel can often be remineralized. We use hydroxyapatite toothpaste, which has been shown to work as well as fluoride in rebuilding enamel and stopping early decay.

How do I know if I have a cavity?

Tooth sensitivity, mild discomfort when eating or drinking something sweet, hot, or cold, or even visible pits or dark spots on your teeth, could all be signs of a cavity. However, many cavities don’t hurt at all until they’re serious. That’s why regular dental checkups matter.
