Dental Fillings in San Marcos

The primary benefit is stopping decay before it reaches the pulp — where it would require a root canal — or destroys enough tooth structure to necessitate a crown or extraction. Beyond that, fillings restore the full function and appearance of the tooth, relieving any sensitivity or pain caused by the exposed decay, and seal the tooth against further bacterial infiltration. Composite resin fillings also bond directly to the tooth, adding a degree of structural reinforcement to the remaining tooth walls. From a cost and health perspective, a filling placed at the right time is one of the highest-value interventions in all of dentistry.

Composite resin fillings last an average of 5–10 years, and many last considerably longer with proper care. The longevity of a filling depends on its size and location, the patient’s bite, and how well oral hygiene is maintained. Fillings in teeth that bear heavy chewing forces — particularly back molars — tend to experience more wear over time. Patients who grind their teeth at night accelerate this wear significantly and benefit from wearing a custom night guard to protect their restorations. Avoiding using teeth to open packaging, chew on hard objects, or bite nails also extends the life of composite fillings considerably.

No. The procedure is performed entirely under local anesthetic — the tooth and surrounding area are fully numbed before any drilling begins. You may feel pressure or vibration during the procedure, but no pain. Some patients experience mild sensitivity in the filled tooth for a few days after the appointment as the tooth adjusts to the new restoration — this is normal and temporary. If sensitivity persists or worsens beyond a week, contact Tree of Life Dentistry for a follow-up.

Sometimes you will notice a cavity yourself — a visible dark spot on the tooth, sensitivity to hot or cold, pain when biting, or food consistently getting stuck in a particular area. But many cavities, especially in their early stages, produce no symptoms at all. This is precisely why routine checkups with digital X-rays every six months are so important — they reveal decay that is completely invisible to the naked eye and to the patient. By the time a cavity causes noticeable pain without any external trigger, it has typically progressed significantly. The most reliable way to catch cavities at the filling stage rather than the root canal stage is consistent preventive care.

Both restore damaged teeth, but they are used at different stages of damage. A filling is appropriate when decay or damage is limited and enough healthy tooth structure remains to support the restoration. A crown — which encases the entire visible tooth above the gumline — is recommended when decay or damage is so extensive that a filling would not have sufficient healthy tooth to bond to reliably, or when the tooth has been structurally weakened to the point where a filling alone would not protect it from fracture. Dr. Shridhar will always recommend the most conservative treatment that fully addresses the problem — if a filling will work, a filling is what she will recommend.

Yes, though it is not common with well-placed composite fillings. A filling can become dislodged if it is subjected to excessive force — biting on very hard foods, grinding, or trauma. Old fillings can also fail over time as the bond between the composite and the tooth gradually breaks down. If a filling comes out, contact Tree of Life Dentistry promptly — even if the tooth is not causing pain. An exposed, previously filled tooth is vulnerable to decay and further damage. In the meantime, dental cement available at most pharmacies can be used as a temporary measure to cover and protect the tooth until your appointment.

Yes — and in several meaningful ways, composite resin is actually superior. Modern composite materials are highly durable and designed to withstand the forces of normal chewing. Unlike amalgam, composite bonds chemically to the tooth rather than relying on mechanical retention, which means less healthy tooth structure needs to be removed during preparation. Composite also hardens instantly rather than requiring a 24-hour curing period, and it does not contain mercury. The perception that amalgam is stronger is a legacy of older, less advanced composite formulations — the materials used today are a significant improvement on those early versions.

Yes, in most cases. Dental fillings for decay are considered a basic restorative service and are typically covered by dental insurance at a meaningful percentage — often 70–80% after the deductible, depending on your plan. The specific material may affect coverage — some plans cover composite resin at the same rate as amalgam, while others cover composite only on front teeth and apply amalgam rates to back teeth. Our team at Tree of Life Dentistry will help you understand your specific coverage before your appointment so there are no surprises.
