Most patients who haven’t had a filling in several years arrive with a clearer picture of the outcome than of the process itself. A dental filling appointment at Coniston Dental Practice is straightforward, and understanding what happens at each stage tends to make the whole experience more manageable.
The Initial Examination and Preparation
Before any treatment begins, we take a proper look at the tooth. This usually means a short clinical examination and, where necessary, a dental X-ray to confirm the depth of the decay and whether the nerve tissue is involved. The information gathered at this stage determines which type of filling material is most appropriate and how extensive the procedure is likely to be.
Once we’ve confirmed the treatment plan, we apply local anaesthetic. The injection itself is the part patients most often anticipate with concern, but modern anaesthetic techniques, including the use of a topical numbing gel before the needle is introduced, make this step far less uncomfortable than it was even a decade ago. We wait until the area is fully numb before proceeding.
And there’s no benefit in rushing that part. Adequate anaesthesia is the foundation of a comfortable filling appointment.
Removing the Decay
With the area numb, we remove the decayed tooth material using a dental drill or, in some cases, a hand instrument. The goal is to remove everything compromised by decay while preserving as much healthy tooth structure as possible. Composite resin, which is the tooth-coloured material we use for most fillings, bonds to tooth structure in a way that allows us to be more conservative than was possible with older amalgam techniques.
Patients sometimes feel pressure or vibration during this stage but should not feel pain. If you feel anything sharp at any point, raise your hand. We’ll stop and top up the anaesthetic before continuing.
The cavity is cleaned and dried before the filling material is applied. For composite fillings, a conditioning agent is applied to the tooth surface, followed by a bonding resin, which creates the adhesive layer between the tooth and the filling material.
Placing the Composite Filling
| Stage | What Happens | Time Taken |
|---|---|---|
| Shade selection | Composite shade matched to your natural tooth colour | 1–2 minutes |
| Conditioning and bonding | Etching gel and bonding resin applied and light-cured | 3–5 minutes |
| Composite placement | Material applied in thin layers, each cured with a light | 5–15 minutes |
| Shaping and polishing | Excess material removed, surface contoured and polished | 5–10 minutes |
| Bite check | Articulating paper used to verify the bite is even | 2–3 minutes |
Composite resin is placed in layers rather than all at once. Each layer is set using a blue curing light before the next is applied. This incremental approach produces a stronger, more dimensionally stable result than placing the material in a single mass. In our experience, taking the extra time to build up the filling properly makes a real difference to the longevity of the restoration.
Checking and Adjusting the Bite
Once the filling is shaped and polished, we check the bite using thin marking paper that leaves a coloured impression on the surfaces where your teeth meet. If the filling is sitting high, we adjust it until the bite feels even across all contact points.
This step matters. A filling that’s left even fractionally too high changes how your teeth meet across the whole mouth, which can cause jaw discomfort and accelerated wear on the new restoration. Most bite adjustments at the end of a filling appointment take less than two minutes.
But it’s worth knowing: if you were still partially numb when the bite was checked and something feels off once the anaesthetic wears off, contact us. Adjusting the bite after the appointment is a simple and quick procedure.
What to Expect Immediately After the Appointment
The anaesthetic will take between one and three hours to wear off fully, depending on the area treated and the amount used. During that time, avoid eating on the treated side and be careful with hot drinks, since you won’t have full sensation to judge temperature accurately.
Some sensitivity in the days following a filling is normal and doesn’t indicate a problem. The tooth has been through a procedure, and it needs time to settle. The NHS dental treatments overview notes that mild discomfort after a filling is expected and usually settles within a week or two. Most patients we see report that any post-filling sensitivity is manageable and resolves within a few days.
- Avoid very hot or cold foods for 24–48 hours
- If sensitivity persists beyond two weeks, get in touch
- A filling that feels high when you bite can be adjusted at a follow-up visit
- Keep brushing and flossing normally around the filled tooth
How Long Does a Filling Appointment Take?
A straightforward single-tooth filling appointment typically takes between 30 and 60 minutes. Larger cavities, fillings involving multiple surfaces of a tooth, or cases where significant decay is close to the nerve will take longer. We’ll give you an honest estimate of time when we confirm the appointment.
Multiple fillings can sometimes be completed in a single appointment depending on the location and extent of treatment, or we may recommend splitting them across two sessions to keep the experience manageable.
