Biomimetic Dentistry in Winnipeg
Save cracked and sensitive teeth — often without a crown or root canal.
Avoiding your favorite foods because of sensitivity? Discomfort with cold, sweets, or chewing? Concerned that a cracked tooth is getting worse? Biomimetic dentistry addresses these problems at their source while preserving your natural tooth — durable, conservative treatment often without traditional crowns or root canals.
Conserve your natural tooth — we remove only what is damaged, rather than reducing the tooth for a crown¹
Protect the nerve — sealing and stabilizing a cracked tooth early often prevents the need for a root canal²
Proven to last — 96% survival at nearly 17 years, across 2,392 bonded restorations³
Usually one or two visits — most treatment is completed efficiently, not stretched across months
Dr. John Weselake has biomimetic training and mentoring through:
What Is Biomimetic Dentistry?
Bio — life. Mimetic — to imitate.
Biomimetic dentistry is a research-driven approach to repairing teeth that restores nature's original engineering. Rather than cutting a damaged tooth down for a crown, we remove only what is diseased, seal the living tooth immediately, and rebuild it with bonded materials that behave like natural enamel and dentin.
A natural tooth is a remarkable piece of engineering: a hard enamel shell over a slightly flexible dentin core, the two grading seamlessly into each other through a natural junction built to distribute stress.⁷ The curved enamel works as a compression dome, converting biting force into compression — which enamel handles superbly — and shielding the dentin beneath from the tensile forces that initiate cracks.⁴ A crown preparation disrupts this design, removing 63–72% of healthy tooth structure¹ and replacing it with a rigid cap. Biomimetic dentistry restores it, rebuilding the tooth so it flexes and absorbs force much like the original.⁵
The strength of the repair rests on the technique. When tooth is prepared to research-defined endpoints and freshly cut dentin is sealed immediately, the adhesive bond reaches roughly the strength of the natural junction that holds a healthy tooth's enamel and dentin together.⁶ ⁷ A bond of that strength allows the restoration and the tooth to carry force as a single unit.
These protocols were developed by Dr. Pascal Magne, Dr. David Alleman, and Dr. Matt Nejad, and are supported by three decades of adhesive-dentistry research. Dr. Weselake trained directly under all three programs.
Why Did My Tooth Crack?
Teeth rarely crack without reason. The most common causes we see:
Old or large fillings, particularly amalgam. Cutting a large cavity removes much of a tooth's strength — in laboratory testing, a wide preparation reduced a premolar's fracture resistance by roughly 60%.⁸ It also changes how the tooth moves under load: an intact tooth flexes only about 3 microns under a firm bite, while a large unrestored cavity can flex toward 180 microns — many times more.⁵ Because amalgam does not bond to the tooth, it sits within it like a wedge, expanding and contracting over years and leaving thin, unsupported cusps that eventually fracture. A bonded restoration works in the opposite way, returning that flex to near-natural levels.⁵
A disrupted compression dome. When enamel is cut in the wrong places, the dentin beneath is exposed to tensile forces it was never designed to withstand — the forces that drive a crack deeper.⁴ This is why a heavily filled or crowned tooth can fracture years later.
Uneven bite forces. When teeth do not meet evenly, a few absorb more force than they were built to handle, and those are the teeth that tend to crack. An uneven bite is also frequently what drives grinding.
Grinding and clenching. These can contribute, particularly at night — and when they do, the underlying bite relationship is often the root cause. A lasting repair addresses the forces on the tooth, not only the crack itself.
Importantly, cracks do not heal. Enamel and dentin cannot regenerate across a fracture line, and the fluid movement within an open crack is what produces the sharp, unpredictable pain with biting and cold.⁹ A crack is either sealed and stabilized or it continues toward the nerve — which is why timing matters.
The Benefits of Biomimetic Treatment
Relief at the source. Sealing exposed dentin corrects sensitivity at its origin rather than masking it with desensitizers, and most patients find the sharp pain settles within a few days.⁹
Conservation and long-term value. Preserving your natural tooth avoids the progression to increasingly invasive procedures. Treating a tooth conservatively now helps you avoid the escalating cost — biological and financial — of the root-canal-and-crown, then extraction-and-implant sequence. One well-executed treatment is generally more economical than years of repair and replacement.
The Importance of Timing
A cracked tooth is, in effect, a race against the crack. While the nerve remains healthy, sealing and stabilizing the tooth early gives it the best chance of staying alive; in clinical studies, cracked teeth treated promptly were more likely to retain a healthy nerve, while those left longer more often required a root canal.² Each week a crack remains open and flexing under biting force, it works a little deeper.⁹
We believe in being straightforward about what this treatment can and cannot do. If a crack has already reached the nerve, biomimetic techniques cannot reverse that, and root canal therapy or extraction may be the appropriate course. We assess each tooth honestly and will tell you plainly which situation applies. Treating a tooth early is the most reliable way to keep it in the conservative category.
Biomimetic Dentistry Compared to a Crown
The conventional approach. A crown requires removing 63–72% of the healthy tooth¹, which permanently reduces its strength and disrupts the compression dome that had protected it from cracking.⁴ Treatment typically spans several appointments, and where old amalgam remains, its stiffness mismatch continues to raise fracture risk over time.
The biomimetic approach. We preserve the maximum amount of natural tooth structure⁶, seal and stabilize the tooth at the source, and rebuild it with bonded materials that flex and carry force like the original.⁵ The dentin is sealed the moment it is exposed, and this matters considerably: sealed immediately, the bond develops its full strength; sealed later, at the cementation appointment in the conventional manner, it can reach as little as 3–17% of that.¹⁰ The most recent clinical review of immediate dentin sealing found higher restoration survival, fewer complications, and significantly less post-operative sensitivity.¹¹ Most treatment is completed in one or two visits.
Why the difference comes down to the bond. A conventional crown doesn't rely on adhesion — cement grips the crown, and the crown carries the load through its own bulk, which is exactly why so much healthy tooth must be removed to make room for it. A bonded overlay replaces only what's damaged and becomes one structural unit with the tooth — carrying force together the way enamel and dentin do in nature — so most of the natural tooth stays intact.
What to Expect
Visit one — diagnosis and stabilization. Under high magnification, Dr. Weselake maps each crack using transillumination and air abrasion — and evaluates how deep the damage runs, including the bite and wear patterns that cause teeth to crack. Decay and cracked structure are precisely disclosed and removed to research-defined endpoints.⁶ Conserving healthy structure is not cosmetic; how much of the tooth remains, and where, largely determines how it will withstand years of biting.⁵ Decay is taken to an objectively clean peripheral seal — deep enough to remove infection, conservative enough to protect the nerve.⁶ The freshly exposed dentin is then sealed the same day with immediate dentin sealing, before contamination can compromise the bond.¹⁰ Smaller repairs are completed in bonded composite in the same appointment; teeth requiring an overlay are left stabilized and comfortable.
Visit two — the definitive restoration. Your custom lithium-disilicate (e.max) overlay is bonded under rubber-dam isolation, the controlled, contamination-free field the research protocols require. We bond with OptiBond FL and Clearfil SE Protect — the two adhesive systems the field regards as gold-standard, and the ones with the best-documented long-term clinical record.¹² You leave with a tooth rebuilt to function like the one nature provided.
Afterward, your restoration is maintained over the long term through biofilm control at your regular Gentle Swiss Clean.
The Protocol
Dr. Weselake follows the protocols refined across three decades of clinical research:
Stress-reduced composite placement (Deliperi–Alleman technique)⁶
Immediate dentin sealing (Magne's protocol)¹⁰ ¹¹
Peripheral seal and resin coating at research-defined margins⁶
Decoupling with time — sequencing the build-up so shrinkage stress never fights the maturing bond¹³
Biomimetic overlay design following established preparation guidelines¹⁴
Each step serves a single goal: a restoration that bonds to, and behaves like, natural tooth structure.

Proven long-term survival. In a prospective study of 2,392 bonded lithium-disilicate restorations followed for nearly 17 years, cumulative survival was 96% — a failure rate of 0.17% per year, with no restorations debonding. Partial-coverage restorations such as the overlays we place performed on par with full crowns, while conserving far more natural tooth.³
Investment. Fees reflect the training and technique this care requires, and they vary with the size and complexity of each tooth — a small bonded composite repair and a full lithium-disilicate overlay are different procedures. Rather than quote a figure that may not fit your situation, we provide an exact, itemized estimate at your consultation, before any treatment begins. Payment is due at time of service. As a courtesy, we can submit to private insurance for your reimbursement.
Patient Experiences
-
It's a conservative way to repair a damaged tooth that keeps as much of your natural tooth as possible. Instead of cutting the tooth down for a crown, we remove only the damaged part, seal the living tooth, and rebuild it with bonded materials that behave like natural enamel and dentin — which typically means preserving the nerve and avoiding a crown or root canal where the tooth still allows it.
-
Most often an old, large filling is responsible. Cutting a wide cavity can reduce a tooth's fracture resistance by roughly 60%⁸, and a tooth that once flexed only slightly under a firm bite can flex many times more once it has been cut.⁵ Amalgam compounds this: because it does not bond, it acts as a wedge, expanding and contracting over years until the thin walls around it fracture. A disrupted enamel compression dome exposes the dentin to forces it was not built for⁴, and an uneven bite concentrates force on a few teeth. A bonded restoration returns that flex to near-natural levels.⁵
-
No. Enamel and dentin cannot regenerate across a fracture line, and the fluid movement within the crack is what produces the sharp pain with biting and cold.⁹ A crack is either sealed and stabilized with a bonded restoration or it progresses toward the nerve — which is why the timing of treatment matters.²
-
The longer a crack goes untreated, the more likely the nerve becomes inflamed beyond recovery. In clinical studies, cracked teeth treated later more often required a root canal.² Sealing the tooth early gives it the best chance of remaining healthy and intact. If a crack has already reached the nerve when we examine it, we will tell you directly — some teeth do require root canal therapy, and early treatment is the most reliable way to avoid that outcome.
-
Many fillings are placed as a single bulk increment and bonded with a one-bottle universal adhesive. It is quick, but compared with the multi-step adhesive protocol we use, it bonds less firmly — bulk placement produces measurably lower adhesion to the cavity floor¹³ — and a rigid filling packed against dentin does not flex as natural tooth does. That mismatch concentrates stress at the bond, the seal gradually breaks down, and the filling begins to leak, which you feel as sensitivity to cold and sweets.⁹ The usual response is a desensitizing agent to quiet the nerve; we do not take that approach, as it masks a failing bond rather than correcting it. Our protocol seals the living dentin immediately¹⁰ and rebuilds the tooth in stress-managed layers¹³ that mimic its natural elasticity, which is designed to keep the bond sealed rather than mask a failing one.
-
A crown bonds far less securely to the tooth than a bonded restoration — with zirconia or metal especially — so it relies on its own bulk, which is why crowns remove 63–72% of the tooth¹ and disrupt the enamel compression dome that protects it from cracking.⁴ A biomimetic overlay bonds to the tooth as one structural unit, preserving natural tooth structure⁶ and the nerve.
-
Yes. When an old amalgam filling is failing, decayed, or cracking — or if you simply prefer to have it replaced — we follow most aspects of the SMART protocol (Safe Mercury Amalgam Removal Technique) to reduce mercury exposure during removal, including rubber-dam isolation and high-volume evacuation. Once the amalgam is out, we rebuild the tooth with bonded biomimetic techniques rather than another large filling, and BPA-free composite can be incorporated on request.
-
Because every tooth is different, fees vary with the size and complexity of the treatment — a small bonded repair and a full lithium-disilicate overlay aren't the same procedure. We provide an exact, itemized estimate at your consultation, before any treatment begins, and as a courtesy we submit to private insurance for reimbursement. Treating a tooth well once is generally more economical than the crown, root canal, extraction, and implant sequence it can help avoid.
