Composite Fillings in Georgetown

Felt something hard in your dinner that wasn’t food? When a filling comes loose, people in Georgetown can call for advice, have the tooth checked and find out whether a new tooth-coloured filling will do the job.

When a filling comes out

A gap where the filling used to be

It usually happens mid-meal. A small piece of something hard turns out to be part of your tooth or an old filling, and your tongue finds a sharp hollow where it used to be smooth.

Many lost or broken fillings can be replaced with composite, a tooth-coloured resin that is bonded into the prepared space and shaped to match the tooth’s original form. Still, a filling that came out may have done so for a reason. Decay underneath, a crack or a large missing wall can mean the tooth needs a different kind of repair, so it should be looked at before anything is replaced.

Call us from Georgetown when it happens. Describe any pain and whether the area is sharp, and we will advise how soon to come in.

Why fillings fail

Clues the dentist looks for

A new filling is one possible response. The exam reveals why the old one let go, how much of the tooth is affected, and whether enough sound structure remains to support another direct repair.

Decay beneath the old filling

New decay can loosen a filling from below. If so, it is removed before the tooth is rebuilt with fresh material.

Tooth broken alongside it

Sometimes the filling is fine but part of the tooth around it has fractured. Composite may handle a limited break; a bigger one, or a crack below the gum, may need more.

A worn or partly lost repair

If only a portion has come away, the rest may or may not be sound. The dentist decides whether to patch, replace the whole filling or recommend another restoration.

A gap can be sensitive to air or cold, which is not unusual. Tell us how strong the feeling is and how long it lasts when you call.

Replacing with composite

Rebuilt to look like tooth

When the space is suitable, composite can restore the tooth in a shade close to its enamel, making it a common choice where appearance matters. It can also be used for selected back-tooth repairs, with the size of the filling and the pressure of chewing taken into account.

It will not suit every gap. The tooth must stay dry while the material bonds, and a large or heavily loaded area might be better served by a stronger restoration. Your old filling material does not decide the new one; the tooth does.

A shade picked for the tooth

The dentist matches the colour to the surrounding enamel, so the new repair blends in.

Keeping what is healthy

Bonding may allow healthy tooth to stay where the condition of the tooth permits.

Commonly a single visit

Many direct fillings are done in one treatment appointment, though the assessment or other care may need extra time.

Getting it replaced

From the empty space to a smooth tooth

Knowing the steps can take some of the worry out of it. Let us know if you need a break, and ask questions whenever they come up.

  1. Find out why it failed

    We hear what happened and look at the tooth and any remaining material. X-rays may be advised if they would show decay or damage below the surface. You will hear the plan, the alternatives and an estimated fee first.

  2. Numb and clear the area

    Local anaesthetic may be used. Leftover filling and any decay are taken out, then the space is isolated from saliva so composite can bond.

  3. Rebuild the missing section

    Resin is placed in layers, each hardened with a curing light, and shaped to restore the chewing surface and the tooth’s contact with its neighbour.

  4. Polish and check how it bites

    The filling is smoothed and your bite tested. You can ask about eating, cleaning or anything that feels unusual before you go.

Once it’s fixed

Helping the new filling last

Follow the advice given for your tooth. If something seems wrong once you are back home in Georgetown, call us; there is no need to wait until a checkup.

Hold off until feeling is back

Avoid chewing on the numb side, and be careful with hot food and drinks so you do not hurt your lip, tongue or cheek.

Report a bite that feels off

Mild sensitivity can occur for a short while. Get in touch if pain increases, sensitivity lingers, or the new filling seems to meet before your other teeth.

Keep decay from returning

Brush using fluoride toothpaste twice each day and clean between teeth daily. Decay at the edges of a filling is a common reason they fail.

If another filling won’t do

Sometimes the tooth asks for more

Ask what each option is meant to accomplish and what the alternatives would mean. The recommendation should rest on how much healthy tooth is left.

When a direct repair will hold

Composite or another filling

Position, moisture control, the size of the gap and your bite all affect which material is used. Discuss the strengths and drawbacks with the dentist.

When walls of the tooth are lost

A crown or onlay

Teeth that have lost a filling more than once, or a large part of their structure, may need a bigger restoration that covers and supports what remains.

When decay has reached the pulp

Root canal treatment

If infection has reached the inside of the tooth, a filling alone will not fix it. The dentist may then explain root canal therapy and the kind of covering the tooth would need afterwards.

Lost filling questions

What to do, and what comes next

Ask about anything that worries you. If you cannot tell what broke, describe what you found and how the tooth feels.

(905) 876-4488
What should I do if a filling falls out?
Keep the piece if you can, rinse gently, and call us. Avoid chewing on that side, and keep the area clean. Severe pain or swelling should be mentioned straight away.
Can I chew on the side with a lost filling?
It is best to avoid it until the tooth has been checked, since the remaining tooth may be weaker and more likely to break. Softer foods on the other side are a sensible stopgap.
Why do fillings come loose?
Common reasons include new decay at the edges, wear over time, heavy biting forces or a crack in the tooth. Finding the cause helps decide whether another filling is suitable.
If my old filling was metal, will the new one be composite?
It may be, if the space suits composite. Large repairs or teeth under heavy load may need a different approach. The dentist will explain the options for that tooth.
Is it normal for the edge of the tooth to feel sharp?
Yes, a gap often leaves a rough edge that your tongue keeps finding. If it is cutting your tongue or cheek, mention it when you call so we can advise you.
Could I need a crown instead of a filling?
Sometimes. If a large part of the tooth is gone or the tooth has cracked, a crown or partial-coverage restoration may protect it better. The exam will show which is appropriate.
