Why Keeping Your Natural Teeth Should Always Be the First Goal

There is a growing trend in dentistry — particularly in the cosmetic and implant sector — towards extraction and replacement as a first-line solution. Teeth that could be saved with skilled endodontic treatment are instead removed. Teeth that could be restored conservatively are replaced with implants. This is, in my view as a clinical professor specialising in cariology and minimally invasive dentistry, a troubling direction.

No restoration — however sophisticated — performs as well as a well-maintained natural tooth. An implant is an excellent solution when a tooth is genuinely lost or unrestorable. But when extraction is chosen for convenience, or because the clinician lacks the skill or inclination to save the tooth, the patient has been poorly served. I have been making this argument in academic and clinical settings for over two decades, and the evidence behind it has only strengthened.

What Is Minimally Invasive Dentistry?

Minimally invasive dentistry (MID) is a philosophy — and increasingly a robust clinical evidence base — that holds that the least intervention necessary to achieve a healthy, functional outcome is always the right intervention. It draws on cariology (the science of dental caries), adhesive dentistry and preventive protocols that have transformed what is clinically achievable in the last generation.

In practical terms, it means: detecting disease as early as possible, when it is most easily managed. Treating with the smallest restoration compatible with the clinical situation. Preserving as much healthy tooth structure as possible at every stage. And supporting patients to prevent recurrence through education and individually tailored preventive care. My own research at Queen Mary University of London has contributed to the UK Department of Health guidelines in this area — the evidence is not marginal, it is central to modern dental practice.

Early Detection Changes Everything

Early-stage caries — the lesions that precede a cavity — can often be remineralised and arrested without any drilling at all. Fluoride application, diet advice and monitoring can stop a lesion that, left undetected, would require a filling within 12–18 months. This is not alternative dentistry — it is evidence-based, published clinical practice that remains underused in general dental settings.

At DentAkademi London, we use CBCT imaging, intraoral scanning and dedicated caries detection tools to identify disease at the earliest possible stage. In my clinical sessions, I routinely see patients who have been told they need fillings or crowns for lesions that, at this stage, are better managed with remineralisation protocols and monitoring. The difference in long-term outcome — for the tooth and for the patient — is substantial.

What This Means for You as a Patient

If you are told a tooth needs to be extracted, it is always worth seeking a second opinion from a specialist endodontist or restorative dentist. Many teeth that are presented as unrestorable can in fact be saved with the right expertise. Once a tooth is extracted, that option is gone permanently — no implant, however well placed, will fully replicate the proprioceptive feedback and structural integration of a natural root.

Similarly, if you are told you need a crown when you currently have a large filling, ask whether a more conservative restoration — an onlay or an overlay — might achieve the same outcome with less removal of healthy tooth structure. The answer may still be a crown, but the question is worth asking, and an honest clinician will welcome it.

A Note on Implants

I want to be clear: dental implants, when genuinely indicated, are a remarkable treatment. We place them regularly at DentAkademi London and the results, in the right cases, are excellent. But “indicated” means the tooth is genuinely unrestorable — not that saving it would require more skill, more time, or a referral to a specialist. The two are very different things, and conflating them does patients a disservice.

Our commitment at DentAkademi London is to give patients the information they need to make genuinely informed decisions — and to offer the full range of options, not just the most convenient ones. That is what I believe good dentistry looks like.
