Treating Badly Discoloured Teeth

A look at the cosmetic improvement options at our Catford dental practice

Few people expect their teeth to remain exactly the same colour throughout their lives.

When we are younger, teeth usually appear naturally brighter, but as the years pass by, many of us begin to notice subtle changes. Perhaps our teeth seem a little darker than they once did. Maybe there are stains that don't seem to disappear no matter how carefully we brush our teeth. In some cases, just a single tooth may become noticeably darker in colour than those around it.

It is one of the most common aesthetic concerns that patients bring to us, and understandably so. A person's smile tends to be one of the first things others notice, and when teeth become discoloured it can affect confidence far more than many people realise.

The good news is that modern dentistry offers a number of possible solutions. The challenge is identifying why the discolouration has occurred in the first place.

Not all staining is the same

One patient may have teeth that have gradually darkened over several decades, while another may have developed a specific stain caused by medication, trauma or a previous dental treatment for example. Two smiles can appear similar at first glance but require entirely different approaches.

This is why a proper assessment is always necessary before deciding on your treatment.

Everyday staining

Many of the things we enjoy regularly can leave their mark over time. Tea, coffee, red wine and certain foods are all likely to contribute to staining. Smoking is another well-known culprit and one that can cause serious issues like periodontitis as well. These changes often occur gradually, making them difficult to notice at first before you eventually realise your teeth look darker than you remember.

In situations like these, professional tooth whitening is often one of the first treatments we discuss.

Teeth whitening

Patients are sometimes surprised by how effective a tooth whitening treatment can be when the underlying teeth are otherwise healthy. By carefully lightening the natural shade of the enamel, it is often possible to achieve a fresher and brighter appearance without altering the teeth themselves.

Deeper staining

Some stains lie deeper within the tooth structure and are less responsive to whitening products. Others may have developed as a result of injury.

A tooth that has suffered trauma, even many years ago, can gradually change colour. Occasionally it darkens to a greyish shade that stands out against neighbouring teeth. In these circumstances, whitening may still play a role, but additional treatment options sometimes need to be considered.

Porcelain veneers

Veneers have been used in dentistry for many years and remain a popular choice for some patients. They cover the visible front surface of a tooth, allowing colour, shape and other aesthetic concerns to be addressed simultaneously.

One of the reasons veneers continue to be so widely used is their versatility.They can be especially  valuable when dealing with stubborn discolouration that has proved difficult to improve through other means as well as restoring chipped or cracked teeth. That said, veneers are not automatically the right answer for every patient. Dentistry has become increasingly conservative over the years and preserving healthy tooth structure remains an important consideration.

Older restorations

We sometimes see patients whose concerns are linked to older dental work rather than the teeth themselves.

A filling placed many years ago may have darkened around the edges. An ageing crown might no longer match the neighbouring teeth. In situations like these, replacing existing restorations can sometimes make a remarkable difference to the overall appearance of a smile.

Interestingly, some patients arrive expecting extensive treatment only to discover that one or two small improvements are enough to address what has been bothering them. This is one of the reasons why consultations are so valuable. What appears obvious in the mirror at home is not always the whole story.

Subtle improvements

In recent years, there has been a move away from the ultra-white smiles that dominated certain celebrity circles. Many patients now tell us they simply want their teeth to look healthy and natural but also a few shades whiter.

The good news for the patients of our smile dentists in Catford is that cosmetic treatments can be personalised to your own requirements. This means that, in many cases, family members may comment that your smile seems brighter. Yet nobody can quite identify what has changed.

Whether your teeth have become stained through everyday habits, darkened with age or developed more significant discolouration for other reasons, there is usually more than one possible solution available.

Exploring options

At our dental practice, we regularly help patients explore the options available to them, from professional whitening through to more comprehensive cosmetic treatments where appropriate. Every smile is different, and so is every treatment plan.

If the colour of your teeth has begun to affect your confidence, arranging a consultation can often be the first step towards finding a solution. You can arrange yours today by calling the Smile Dental Practice on 020 8314 5066.
