How We Decide Which Teeth Need RCT, Crowns, or No Treatment
Not every painful tooth needs a root canal. Not every worn tooth needs a crown. And sometimes, the safest treatment is no treatment at all.
In Full Mouth Reconstruction, most failures happen because teeth are treated in isolation—without understanding bite forces, tooth vitality, and long-term load.
Our decisions at our Sector 51 & 74 clinics are not made tooth-by-tooth. They are made by analyzing the entire mouth, the bite, and how teeth work together over time.

Why Every Worn Tooth Does NOT Need RCT
The Common Misunderstanding
When a tooth looks short, flat, or sensitive, many people are told they need a root canal. The truth is simple — a worn tooth and a dead tooth are not the same.
Most Worn Teeth Are Still Alive
In most patients, worn teeth are still vital. The nerve adapts slowly to wear over many years. Mild or occasional sensitivity does not automatically mean nerve damage.
What Actually Causes Tooth Wear
Tooth wear is usually caused by grinding, clenching, strong jaw muscles, or an unstable bite — not infection. Doing a root canal in such cases removes a healthy nerve without correcting the real cause.
What We See Repeatedly
Many patients come to us after being advised multiple root canals. On proper testing, the teeth are alive and stable. Once the bite is corrected, these teeth continue to function comfortably for years — without any root canal treatment.
Our Decision-Making Approach
Every worn tooth is tested for vitality. Bite forces are analysed. Long-term load is assessed. Only then do we decide whether a root canal is truly required — or whether the tooth should be preserved.

How Sensitivity Testing Actually Works
Pain Is Not the Test
Many people think, “If it hurts, the nerve is dead.” That is incorrect. Pain alone does not decide root canal treatment.
What We Are Actually Checking
Sensitivity testing checks whether the nerve is alive, how it responds, and how quickly it recovers. A living nerve reacts and settles. A damaged nerve reacts abnormally or not at all.
Short Pain vs Lingering Pain
A quick sharp response that settles is usually a healthy or adapting nerve. Pain that lingers for long or keeps increasing is a warning sign. This distinction is critical and often missed.
Why One Test Is Not Enough
Sensitivity testing is never done in isolation. We compare teeth, repeat tests, and relate findings to bite forces, X-rays, and wear pattern. No single test decides RCT.
How This Prevents Unnecessary RCT
By understanding nerve behaviour, we avoid treating pain blindly. Many teeth that test vital are protected and preserved instead of being sent for root canal treatment.

Role of Bite Forces in Deciding Treatment
Teeth do not fail only because of decay or infection. Very often, they fail because of excess or uneven bite forces.
Ignoring bite forces is one of the main reasons why crowns crack, root canals fail, and full-mouth cases relapse. Every tooth is designed to handle a certain amount of load.
When bite forces increase due to grinding, clenching, or loss of back teeth, even healthy teeth begin to show wear, cracks, and sensitivity. This does not automatically mean the nerve is damaged.
In many patients, the real problem is not inside the tooth, but how the tooth is being loaded during chewing and at rest. If these forces are not identified and corrected, any treatment done on the tooth alone becomes short-lived.
When bite forces are the root cause, doing a root canal does not solve the problem. The tooth may feel better temporarily, but it continues to take excessive load. Over time, this leads to fractures, crown failure, or implant overload.
Structural Integrity
When Crowns Are Protective vs Destructive
Dental crowns are powerful tools when used correctly. However, if used for the wrong reason, they can shorten a tooth’s life instead of protecting it.
A crown is protective when:
- The tooth is structurally compromised but biologically stable.
- The nerve is confirmed healthy through vitality testing.
- Bite forces are properly analyzed and controlled.
A crown becomes destructive when:
- It is placed without identifying the cause of tooth wear.
- Heavy grinding or bite imbalances are left uncorrected.
- The crown simply absorbs the same destructive forces that broke the natural tooth.
In these cases, crowns often crack, loosen, or cause post-treatment pain, eventually pushing the tooth toward an unnecessary root canal.
A Shift in Diagnosis
Why “Do RCT First, Crown Later” Is Outdated Thinking
For many years, dentistry followed a simple sequence: pain first, root canal first, crown later. This approach may work for isolated teeth, but it often fails in patients with multiple worn or overloaded teeth.
The main problem with this thinking is that it treats symptoms instead of causes. Pain or sensitivity is often driven by excessive bite forces, grinding, or loss of support — not infection inside the tooth.
Over time, this leads to common failures: post-RCT pain, cracked crowns, vertical fractures, and teeth that eventually need extraction. The sequence was correct, but the diagnosis was incomplete.

Conservative Clinical Care
When We Wait and Observe Instead of Treating
In dentistry, doing more is not always doing better. There are situations where the safest and most responsible decision is to wait, monitor, and reassess rather than treat immediately.
Teeth that are worn, sensitive, or mildly painful are often assumed to need urgent procedures. However, many of these teeth are vital, stable, and adapting, especially in patients with long-standing bite imbalance or grinding.
In such cases, immediate root canal treatment or crowning can lock the tooth into a cycle of overtreatment. Once the nerve is removed or the tooth is cut, there is no way to reverse that decision.
Predictable Outcomes
How This Approach Reduces Failures Long-Term
Dental failures rarely happen suddenly. They build up slowly when diagnosis is rushed and treatment decisions are made tooth-by-tooth instead of looking at the full mouth.
When teeth are treated without understanding bite forces, vitality, and long-term load, common problems follow — cracked crowns, repeated root canal failures, fractured teeth, and eventually tooth loss.
A bite-driven, prosthodontic approach reduces these failures by addressing the reason the tooth is under stress, not just the symptom.
This approach is especially important in full mouth reconstruction cases, where mistakes multiply across many teeth. When forces are balanced and teeth are planned together, restorations last longer and feel more natural.
This philosophy is central to Full Mouth Reconstruction in Gurgaon, where success is measured in decades, not just immediate relief.
How We Make Treatment Decisions — In Simple Terms
We do not treat pain alone.
We do not decide RCT based only on X-rays.
We do not crown teeth without understanding bite forces.
We test whether a tooth is alive before planning treatment.
We look at how all teeth work together, not one tooth at a time.
This structured decision-making is what separates short-term dental fixes from long-term functional outcomes. It allows us to preserve healthy teeth, avoid unnecessary procedures, and plan treatment that actually lasts.
This framework is followed consistently in complex cases involving worn teeth, multiple crowns, and full mouth reconstruction planning across our Gurgaon clinics.

Why This Decision Framework Matters
These decisions are not made casually. They require an understanding of tooth biology, bite mechanics, and long-term prosthodontic planning.
A prosthodontist is trained to look beyond single teeth — to study how teeth, bite forces, restorations, and jaw function interact over time. This perspective is essential when deciding whether a tooth needs RCT, a crown, or preservation.
