Composite resin fillings restore teeth with a durable, mercury free material matched precisely to your enamel shade, strengthening the tooth as it repairs it. Composite is the standard for fillings at our Rancho Bernardo office because it bonds to tooth structure rather than merely occupying space, conserves more healthy tooth than metal ever did, and disappears completely into your smile. Modern composites are strong enough for molars and beautiful enough for front teeth alike.
The resin bonds directly to your tooth structure in thin layers, each cured rock hard with a light, reinforcing the tooth from within rather than wedging into it the way amalgam does. We match the shade to your exact enamel before starting, sculpt the anatomy back to natural contours, dial in your bite, and polish to a seamless finish. The bond seals margins tightly, which is much of why composites protect so well.
Beyond looking invisible, bonded composite supports the remaining tooth, requires less drilling than metal fillings since it does not need mechanical undercuts, contains no mercury, and does not expand and contract with temperature the way metal does, a known crack driver in older amalgam teeth. The result is a repair that strengthens rather than merely occupies, and one nobody will ever spot in a photograph or across a dinner table.
Composite Resin Fillings in Rancho Bernardo | RB Dental Arts
Mercury free fillings matched precisely to your natural shade.
Choose composite for new cavities anywhere in the mouth, or to replace aging silver fillings you would rather not see when you laugh, especially ones showing dark margins or cracks after decades of service. We replace old amalgam when it is failing or when you want it gone, and we will tell you honestly which of yours are still serving fine. For anyone bothered by metal glinting in their smile, the upgrade is quick and complete.
Visits are efficient and gentle: thorough numbing, careful removal of decay or old material, unhurried layering and sculpting, and a final polish. Most single fillings finish in well under an hour, and once the numbness fades, the tooth simply feels and looks like a tooth. Patients replacing visible metal fillings get the extra satisfaction of the before and after, and most genuinely cannot tell afterward which tooth was ever filled.
A single composite filling takes 30 to 60 minutes, and neighboring fillings are typically grouped into one visit to spare you repeat numbing. The material cures to full strength instantly, so you eat as soon as the anesthetic wears off, about two to three hours. Expect seven to ten years or more of reliable service from a well placed composite, monitored at every checkup and easily repaired or refreshed if margins ever wear.
A few days of mild cold sensitivity after placement is normal and fades; a bite that feels high once numbness clears deserves a quick call, two minutes of polishing fixes it. Very deep fillings near the nerve occasionally progress to needing root canal treatment despite perfect work; when that risk exists, you will hear it from us before we begin, never after. Composite resists stains well but not infinitely, coffee and red wine eventually tint margins, and polish visits keep everything matched.
Recovery is the rest of your afternoon: numbness for two to three hours, possible mild tenderness at the injection site until tomorrow, brief cold sensitivity settling over days. Chew cautiously until feeling returns, the only real hazard is biting a numb cheek, then eat normally. From there the filling asks nothing special: brush, floss, keep your checkups, and let it quietly do its job for the next decade.
