Patients often assume that brushing twice daily and avoiding sugar should be enough to prevent dental problems. Yet many people still experience unexpected tooth decay, broken fillings, gum disease, or even the need for dental implants.
A recent article in The Times highlighted a dental patient facing a costly dental implant after years of being “filling-free,” raising an important question: why do teeth sometimes fail despite good oral hygiene?
At Thames Street Dental, we see this scenario regularly. Someone with good dental habits suddenly develops repeated decay, gum inflammation, or unexplained dental problems. Increasingly, research suggests the answer may lie in your oral microbiome — the complex community of bacteria living in your mouth.
Your mouth contains over 700 species of bacteria, along with fungi, viruses and yeasts. In a healthy mouth, these microorganisms exist in balance. When this balance shifts, problems can develop such as:
Some bacteria are protective, while others contribute to acid production and tissue breakdown. This is why two people with similar brushing habits can have very different dental outcomes.
If you’ve experienced repeated dental problems, early detection through regular examinations is essential.
Saliva microbiome testing is a relatively new concept in dentistry. The idea is simple: a patient provides a saliva sample, which is analysed to identify bacterial levels and risk markers.
The results may highlight:
This allows dentists to tailor preventive care rather than waiting for problems to develop. This complements modern preventive dentistry, similar to early decay screening we offer in Kingston at Thames Street Dental.
Many patients feel frustrated when they develop cavities despite brushing and flossing. Oral health depends on multiple factors:
If you suspect teeth grinding, you may benefit from assessment and protective options such as a mouthguard.
Researchers are increasingly exploring the connection between oral bacteria and systemic health conditions, including:
While this research is still developing, the concept is clear: your mouth is the gateway to your body. Inflammation and harmful bacteria in the mouth may influence overall health.
The patient in the article faced a costly dental implant — something many people hope to avoid. While dental implants are an excellent long-term solution, prevention is always preferable.

The oral microbiome is the collection of bacteria living in your mouth. A balanced microbiome supports healthy teeth and gums.
Not directly. They assess bacterial risk factors that may increase cavity risk.
As of the time of writing this blog post (April 2026) – Not yet. They are emerging tools and not standard dental practice.
This may be due to bacterial imbalance, acidic saliva, grinding, diet or genetics.
Yes. Early detection and prevention reduce risk of tooth loss.
Yes. Grinding weakens enamel and cracks fillings.
Most patients benefit from check-ups every 6 months. Please see The Importance of Regular Dental Check-Ups in Kingston for more information.
Good oral hygiene, reduced sugar frequency, hydration and regular dental visits help maintain balance.
