When decay extends beyond what a standard filling can cover
Porcelain onlays are larger than inlays — they extend over one or more cusps of the tooth, making them the right choice when damage or decay reaches beyond the center cavity. Like inlays, they are custom-made from dental porcelain and permanently bonded for a strong, natural result.
- Covers one or more cusps for greater damaged-area restoration
- Matched to your tooth’s color, texture, and natural luminescence
- Permanently bonded — stronger and longer-lasting than metal alternatives
Why old metal fillings eventually destroy the teeth around them
Metal fillings are not bonded to the tooth. They rely on tight packing to stay in place, which exerts constant outward pressure on the surrounding tooth structure — expanding the cavity over time.
Temperature changes make this worse. Metal expands when heated and contracts when cooled, creating a repeated stress cycle that cracks enamel and fractures cusps. Porcelain onlays bond directly to the tooth instead of pushing against it, stopping this cycle before more of the tooth is lost.
Why choose porcelain onlays?
Porcelain onlays restore more of the tooth than a standard filling — without the downsides of metal or the full coverage of a crown.
Unlike inlays that restore only the area between cusps, onlays extend over one or more cusps to address larger zones of damage or decay. This makes them the ideal mid-range restoration — more protective than a filling, less invasive than a full crown.
Each onlay is crafted from specially formulated dental porcelain, custom-matched to the color, texture, and luminescence of your natural tooth. The material interacts with light the same way enamel does, making the restoration virtually invisible.
Porcelain onlays are permanently bonded to the tooth rather than packed in with pressure. This bond adds structural support to the remaining tooth, improving and strengthening it — the opposite of what metal fillings do over time.
Dental porcelain does not expand or contract with temperature changes the way metal does. This eliminates the thermal stress cycle that causes metal fillings to gradually crack and fracture the surrounding enamel over years of use.
Porcelain onlays are built from highly durable dental porcelain designed to withstand everyday biting and chewing forces. With regular check-ups and proper care at home, a porcelain onlay provides a stable, attractive, and long-lasting restoration.
