Dental Fillings in Hamilton, ON — White Composite Fillings at Red Rose Dentistry

Red Rose Dentistry uses tooth-coloured composite resin fillings for all new restorations. We have not placed silver (amalgam) fillings in years — not because of the mercury controversy (the evidence on amalgam safety is more nuanced than headlines suggest) but because composite is simply better: it bonds to tooth structure, requires less healthy tooth removal, matches the natural colour of your teeth, and does not conduct temperature changes that cause post-filling sensitivity.

How We Find Cavities You Cannot Feel

Early decay is completely painless — by the time a cavity hurts, it has usually reached the inner dentin layer or is approaching the pulp. We use three tools to find cavities before they become symptomatic:

1. Bitewing X-rays: The primary tool for finding cavities between teeth (interproximal decay), where no probe or mirror can reach. A cavity between two back teeth can grow for years without any symptom before it is large enough to see or probe.
2. Visual-tactile examination: A dental explorer probe is used on chewing surfaces to detect soft spots in the enamel
3. Transillumination: A bright light shone through the tooth — cracks and decay show as dark shadows

The Composite Filling Process — Step by Step

Most patients overestimate how involved a filling is. Here is what actually happens during a standard composite filling at Red Rose:

1. Anaesthesia (5–10 min total): Topical gel applied to the gum for 60 seconds. Anaesthetic injected slowly — this is where discomfort can occur, and slow delivery is what prevents it. We wait 3–5 minutes to confirm numbness before starting.
2. Decay removal (5–15 min): The decay is removed with a dental drill and hand instruments. You will feel vibration and hear the drill — no pain on the tooth itself (it is numb). The goal is to remove only diseased tissue — we try to conserve as much healthy tooth as possible. This is where composite’s advantage over amalgam matters: composite bonds to enamel, so preparations can be more conservative.
3. Etching (1–2 min): A mild phosphoric acid gel is applied for 15 seconds to microscopically roughen the enamel surface — this creates the mechanical bond that holds the composite to your tooth. The gel is rinsed off and the tooth is dried.
4. Bonding agent (1 min): A thin adhesive layer is painted onto the etched surface and light-cured for 10 seconds.
5. Composite placement (5–15 min): Composite resin is placed in 2mm increments, each layer cured for 20 seconds with a blue UV curing light. Layering prevents the composite from shrinking away from the cavity walls as it polymerizes.
6. Bite check and adjustment (5 min): Articulating paper checks your bite. Any high spots are ground down until the bite is level. This step matters — a filling that is even 0.1mm too high will cause jaw pain.

Frequently Asked Questions — Dental Fillings in Hamilton

Will I feel anything during the filling?

No — not on the tooth. The anaesthetic numbs the tooth, surrounding gum, and a portion of the jaw/lip depending on where the injection is placed. You will feel vibration from the drill (a physical sensation your body registers, but not pain), occasional pressure, and the sensation of water/air spray. If you feel any actual pain during the procedure, we stop and add more anaesthetic — no exceptions.

My tooth is sensitive after a filling. Is that normal?

Yes, for up to 2–4 weeks. Composite fillings cause a small amount of polymerization stress on the surrounding dentin as the material hardens. Cold sensitivity is the most common complaint. This resolves on its own. If sensitivity is severe, contact us — it is occasionally necessary to adjust the bite further or, rarely, to place a desensitizing liner.

How long does a composite filling last?

With normal care: 8–12 years average for medium-sized composite fillings. Small fillings on non-stress-bearing surfaces can last 15+ years. Large fillings near the gum or in high-force areas may need replacement sooner. Grinding accelerates filling breakdown — ask about a night guard if you grind.
