Common Dental Issues and Their Solutions

Most dental problems start quietly. A twinge of sensitivity, a spot of bleeding when you brush, a tooth that catches when you bite. Left alone, small issues like cavities, gum disease and decay can turn into painful, expensive ones. The good news is that nearly all of them are preventable, and most are easy to catch early once you know what to look for.

This guide covers the three most common problems we see at the practice, how to spot them, and what actually helps. It also looks at when crooked teeth are worth treating, and answers the questions patients ask us most.

Cavities

A cavity is tooth decay that has broken through the enamel. It happens when plaque, the sticky film of bacteria on your teeth, feeds on sugar and produces acid, and that acid wears the enamel down over time. The process is gradual, which is why cavities often go unnoticed until they cause sensitivity, a visible dark spot, or pain.

The usual culprits:

• Gaps in brushing and flossing that let plaque build up
• Frequent sugary or acidic food and drink, which feeds the bacteria
• A dry mouth, since saliva does a lot of the natural cleaning

Caught early, decay can sometimes be halted with fluoride and better daily care. Further along, it usually means a filling, or a crown if the tooth is badly affected. Six-monthly check-ups are the simplest way to catch it before it gets that far.

Gum Disease

Gum disease starts as gingivitis: mild inflammation, a little redness, some bleeding when you brush. At this stage it is reversible. Left untreated it can progress to periodontitis, where the gum pulls away from the tooth and the bone supporting it begins to break down. That is what eventually loosens teeth, so early action matters.

Keeping it at bay comes down to a few things:

• Brush twice a day and floss to clear plaque from the gumline
• Stop smoking if you smoke, as it is one of the biggest risk factors
• See a hygienist regularly so anything early gets caught

Treatment ranges from a professional clean and scale through to deeper cleaning below the gumline if it has progressed. Our dental hygiene service, which you can book directly, is the front line for this.

Preventing Tooth Decay

Prevention is far less hassle than treatment, and most of it is reassuringly simple:

• Brush twice daily with a fluoride toothpaste, and floss once a day
• Go easy on sugary snacks and drinks, especially between meals
• Keep up regular check-ups so problems are spotted early
• Ask about fluoride treatments or sealants, which add a protective layer for teeth prone to decay

Modern dentistry helps too. Digital imaging lets us see early decay we might otherwise miss, and minimally invasive techniques mean we can treat it sooner and more conservatively. None of it replaces the daily basics, but it does mean fewer surprises.

When Teeth Need Straightening

Crooked or crowded teeth are not only a cosmetic concern. They can be harder to clean, which raises the risk of decay and gum problems, and a poor bite can cause jaw discomfort over time. Common issues include overbites, underbites, crowding and gaps.

There are more discreet options than there used to be. Alongside traditional braces, clear aligners like Invisalign straighten teeth without the visibility of metal, and treatment is tailored to your teeth. A quick assessment is usually enough to tell you whether it is worth doing. You can read more on our orthodontics and Invisalign page.

Frequently Asked Questions

How do routine check-ups prevent bigger problems?

They catch things early. Cavities, gum disease and enamel wear are all far easier to deal with before they cause symptoms. A six-monthly check-up plus a professional clean keeps plaque down and flags anything developing.

What is the best way to look after my teeth at home?

Brush twice a day with fluoride toothpaste, floss daily to reach what the brush misses, and consider an antimicrobial mouthwash. Simple, consistent habits do more than anything expensive.

Why are my teeth sensitive, and what helps?

Sensitivity usually comes from worn enamel or receding gums. Desensitising toothpaste and cutting back on acidic food and drink often help. If it persists, it is worth getting checked, as there is usually a treatable cause.

When is it a dental emergency?

Severe pain, a knocked or broken tooth, or sudden swelling all warrant prompt attention, and the sooner it is seen the fewer complications. See our emergency appointments page if you need to be seen quickly.
