Key Takeaways
- Swelling, bruising, mild bleeding, and soreness are normal after dental implant surgery and typically improve within the first week.
- Persistent pain, worsening swelling, infection, prolonged numbness, or a loose implant should be assessed by a dentist promptly.
- Good oral hygiene, regular dental reviews, and managing risk factors such as smoking and uncontrolled diabetes can help reduce complications.
Tooth decay eats into the enamel and dentine underneath it, and once a cavity forms, the tooth can’t repair itself. A filling removes the damaged part of the tooth and rebuilds the missing structure with a material shaped to match the tooth’s original form. Composite resin is one of several filling materials, and the one most often used on teeth that show when you smile or talk.
What are Composite Dental Fillings?
Composite dental fillings, also called resin fillings, mix plastic resin with finely ground glass particles into a tooth-coloured paste. A dentist shapes and hardens this paste directly inside the cavity, so the filling becomes part of the tooth’s surface rather than a separate piece dropped into place. This direct, chairside application separates composite from indirect restorations like inlays, onlays, or crowns, which a lab builds outside the mouth first and a dentist cements in on a second visit.
Dentists use composite resin most often to fill cavities caused by decay, but the same material repairs chipped, cracked, or worn teeth without a lab-made restoration. It holds up under normal chewing pressure on both front and back teeth, though heavy grinding wears it down faster than it wears down amalgam or gold.
Benefits of Composite Fillings
Composite resin’s main advantages come down to how closely it matches a natural tooth and how little of the tooth needs removing to place it.
Natural Appearance
A dentist tints composite resin to match the surrounding teeth before placing it, which keeps the repair from standing out on front teeth or anywhere else visible when you smile. Older amalgam fillings sit as a visible grey-silver patch by comparison, one reason patients often ask about replacing them.
Strong and Durable
Composite resin withstands the pressure of normal chewing on both front and back teeth. It bonds directly to the tooth surface, which adds structural support beyond filling a hole.
Less Drilling Required
Bonding lets a dentist remove less healthy tooth structure than amalgam requires, since amalgam needs a mechanically retentive shape cut into the tooth to hold it in place. Preserving more of the original tooth keeps it structurally stronger over the long run.
Versatile for Various Repairs
Beyond cavities, composite resin repairs chips, cracks, and teeth worn down by grinding. One material covers several common repair jobs, part of why it has become the default choice for visible teeth.
Less Sensitivity Compared to Metal Fillings
Composite conducts less heat and cold than a metal filling, so hot coffee or cold water is less likely to cause a sharp twinge right after treatment. Persistent tooth sensitivity after a filling is uncommon but worth mentioning at a follow-up visit if it hasn’t settled within a few weeks.
What are the steps involved in the composite filling procedure?
A composite filling takes one visit from start to finish, usually 20 to 60 minutes depending on the size and location of the cavity.
Initial Examination and Preparation A dentist examines the tooth and may take an X-ray to see how far the decay extends. The findings tell the dentist how much of the tooth to remove.
Anaesthesia Local anaesthesia numbs the tooth and surrounding gum before any drilling starts, so the rest of the procedure stays comfortable.
Decay Removal The dentist removes the decayed part of the tooth with a drill or laser, clearing the area down to healthy structure. Leaving any decay behind risks the filling failing early.
Tooth Preparation The dentist cleans out debris and bacteria, then etches the surface to create a slightly rough texture that helps the bonding agent grip the tooth.
Bonding Agent Application A bonding agent goes on next, acting as the adhesive layer between tooth and filling. A curing light hardens it in place within seconds.
Composite Resin Application The dentist builds the resin up in layers, shaping each one to the tooth’s natural contours and hardening it under the curing light before adding the next. Layering this way controls shrinkage and keeps the fit precise.
Shaping and Contouring Once the resin is fully placed, the dentist shapes and polishes it to match the surrounding tooth structure, so it feels and looks like the rest of the tooth.
Final Adjustments (Check Your Bite) The dentist checks how the upper and lower teeth meet once the filling is in place and adjusts the height until the bite feels even. A filling placed even slightly high is one of the causes behind a tooth filling causing bite imbalance that shows up days after treatment, which is why dentists check it before finishing up.
Difference between Composite filling and Amalgam fillings
Composite and amalgam fillings both repair a cavity, but the material and the amount of tooth removed to place them differ. Composite resin bonds chemically to the tooth, so a dentist removes only the decayed part before shaping it into place. Amalgam relies on mechanical retention, which means cutting a slightly larger, undercut shape into the tooth so the metal has something to lock into.
Dentists have used amalgam fillings for over a century, and the material holds up well under heavy chewing pressure, particularly on back teeth. The trade-off is colour: amalgam looks silver-grey against natural teeth, while a dentist shade-matches composite to blend in.
Composite tends to cause less sensitivity to hot and cold than amalgam, since the resin conducts less temperature change into the tooth. The mercury content in amalgam has raised concerns for some patients over the years, though studies have generally found the amount used in fillings safe. Composite resin contains no mercury.
Composite is one of several tooth-coloured options. Ceramic fillings cost more and resist staining longer, and a dentist can advise whether that trade-off makes sense for a specific tooth. Glass ionomer and gold fillings round out the types of dental fillings available, each suited to different parts of the mouth and different budgets.
How long do composite dental fillings typically last?
Most composite fillings last 5 to 7 years, and some hold up for a decade or longer with consistent care. Actual lifespan depends on where the filling sits in the mouth, how well it’s cared for, and how much chewing pressure it takes on day to day.
Composite handles normal chewing pressure well on both front and back teeth, but it wears down faster than amalgam under constant heavy stress. A few habits extend a filling’s working life:
- Keep up regular brushing and flossing. This limits plaque and tartar buildup around the filling’s edge, where new decay is most likely to start.
- Go easy on hard and sticky foods. Ice, hard candy, and chewy caramel can chip or dislodge a filling over time.
- Keep to a regular dental check-up schedule. A dentist can catch early wear or a small crack before it turns into a bigger repair.
- Wear a mouthguard for bruxism. Grinding puts far more pressure on a filling than normal chewing does, so a mouthguard protects it overnight.
- Cut back on staining foods and drinks. Coffee, tea, red wine, and tobacco can discolour composite over time, unlike some other materials.
- Know what to expect right after the appointment. Mild sensitivity for a day or two is normal, and what to do after a dental filling covers eating, drinking, and brushing for that first stretch.
- Address changes promptly. Contact a dentist if sensitivity, pain, or a change in the filling’s fit shows up between visits. Casa Dental’s branches across Singapore offer assessments if something feels off with an existing filling.
How much do composite fillings cost?
The price of a composite filling depends on how large the cavity is, how many tooth surfaces need rebuilding, and whether it’s a straightforward repair or a more complex one. Clinic location plays a role too, along with whether the case needs X-rays or extra visits alongside the filling itself.
A full breakdown of tooth filling cost in Singapore by material and complexity helps set expectations before a consultation. Your dentist confirms the exact price and any CHAS or MediSave eligibility for your specific case at that visit.
Are Composite fillings safe?
Composite dental fillings have a strong safety record and suit most patients. Dental health authorities test and approve the materials for biocompatibility before they reach a clinic.
Biocompatibility. The body generally tolerates composite resin well, and allergic reactions are rare.
Absence of mercury. Unlike amalgam, composite contains no mercury, which some patients prefer to avoid regardless of amalgam’s safety record.
Minimal sensitivity risk. Composite conducts less heat and cold than metal fillings, which reduces discomfort with hot or cold food and drink.
Durability and strength. Composite bonds directly to the tooth and preserves more of the original structure, which supports the tooth’s long-term integrity.
Potential concerns. A small number of patients react to the materials used, and composite fillings generally don’t last as long as amalgam in high-pressure areas. Regular check-ups catch most issues before they become a bigger repair.
Is a Composite Filling Right for You?
Composite suits most cavities, chips, and cracks, especially on teeth that show when you talk or smile. A large cavity on a back tooth under heavy grinding pressure sometimes holds up better with a different material, and that call comes down to what a dentist sees during examination. Raising cost, expected lifespan, and any material preference at that first visit gets the decision made on the full picture, not a guess.
Frequently Asked Questions
How long should I wait to eat after a composite filling?
Composite hardens fully under the curing light during the appointment, so there’s no need to wait hours before eating the way some older filling materials required. Stick to softer foods on that side of the mouth for the rest of the day if the area still feels numb from the anaesthetic. What to do after a dental filling covers the fuller list of do’s and don’ts for that first 24 hours.
Is a composite filling covered by CHAS or MediSave?
CHAS and MediSave apply to different treatments under different rules, and coverage for a filling depends on the specific scheme and individual eligibility. The tooth filling cost guide breaks down which fillings typically qualify, and your dentist confirms the exact eligible amount at consultation.
Is a composite filling as strong or permanent as an amalgam filling?
Every filling material wears down eventually, composite and amalgam included. Composite holds up well under normal chewing pressure but wears faster than amalgam under heavy grinding, one reason a dentist checks bite force and grinding habits before recommending one material over the other.
What's the difference between composite and ceramic fillings?
Ceramic fillings cost more than composite and resist staining better over time, often lasting 15 years or longer in the right spot. Composite is quicker to place in a single visit and costs less upfront, and a dentist can advise which trade-off fits a specific tooth and budget.
