Why Do I Need a Filling? Dental Fillings in Surbiton Explained

Why Do I Need a Filling? Dental Fillings in Surbiton Explained

Post by : Dr Jack Connan BDS GDC No. 277529 | 2 October 2025

It often starts with something small. A bit of sensitivity when you bite into a biscuit, a sharp twinge with a cold drink, or a tiny chip you can feel with your tongue. You book a check-up “just in case” and then your dentist says you need a filling. Suddenly you’re wondering: why do I need a filling and what happens if I leave it?

At Surbiton Dental, we see this scenario every week. The good news is that modern dental fillings that Surbtion patients receive are designed to be comfortable, conservative and long-lasting and they play a key role in protecting your tooth from further damage.

What Are Dental Fillings and How Do They Work?

A filling is a small dental restoration treatment used to repair a tooth that has been damaged by decay or minor fractures. The aim is to remove the weakened area and restore the tooth’s shape and strength so you can chew comfortably again.

There are a few main types of dental fillings:

In a typical tooth filling treatment, your dentist will:

• Numb the tooth and the surrounding area.
• Gently remove the decayed or damaged part of the tooth.
• Clean and prepare the cavity.
• Place the filling material in layers
• Shape and polish it so it feels smooth and comfortable when you bite.

This is how fillings work to seal the cavity, protect the nerve inside the tooth and restore your bite.

What Causes Cavities and When Do I Need a Filling?

Cavities form when bacteria in plaque feed on sugars and produce acids that gradually dissolve the enamel. Over time, this can create a hole in the tooth, which needs tooth cavity treatment.

Common factors that cause cavities include:

• Frequent sugary snacks and drinks.
• Acidic drinks such as fizzy drinks and fruit juices.
• Not brushing or flossing thoroughly.
• Missing regular dental check-ups.
• A dry mouth, which reduces natural protection from saliva.

Once a cavity has formed, brushing alone can’t reverse it. That’s when tooth decay treatment with a filling is usually needed to stop the decay from getting closer to the nerve.

Teeth Cavity Treatment: How We Treat Cavities at Surbiton Dental

If you need teeth cavity treatment, your dentist will talk you through your options in plain language. At Surbiton Dental, this usually involves:

• Assessing the tooth visually and with X-rays.
• Explaining the size and position of the decay.
• Discussing which filling material is most suitable.
• Planning a comfortable, conservative dental restoration treatment.

Modern dental fillings are designed to remove as little healthy tooth as possible. By treating cavities early, we can usually keep treatment simple and help you avoid more complex procedures later on.

Signs You Need a Filling: Do I Need a Filling?

Sometimes cavities are completely silent at first, which is why routine check-ups matter. But there are also common cavity symptoms to watch for. Typical signs you need a filling include:

• Sensitivity to hot, cold or sweet foods in one tooth.
• A dull ache that comes and goes in a particular area.
• Food gets stuck in the same place between teeth.
• Rough edges or a visible hole you can feel with your tongue.
• A filling that has chipped, cracked or fallen out.

If you’re asking yourself, “Do I need a filling?” it’s worth getting it checked. The sooner we see you, the more likely it is that we can treat the problem with a straightforward tooth filling treatment rather than something more involved.

Conclusion: Why a Filling Is Often the Best Option
