When a lot is going wrong in your mouth, the plan matters more than the procedures.

Complex dentistry is not one procedure

Most dental websites are organized by procedure: crowns on one page, implants on another, gum treatment on a third. That works when you have one problem. It stops working when you have several, because the real question is no longer "what does this tooth need?" It's "what is happening in this mouth, and in what order should it be addressed?"

The patients we see for complex care usually arrive with some combination of the following:

• Crowns or bridges that are failing or have failed before
• Large, aging fillings doing more work than a filling should
• Cracked or fractured teeth
• Missing teeth, replaced or not
• Existing implants that need to be worked around
• Root canal-treated teeth with uncertain prognosis
• Gum (periodontal) disease, active or treated
• A bite that has shifted, collapsed, or become unstable
• Teeth visibly worn down or getting shorter
• Recurrent decay around older dentistry
• Previous dental work reaching the end of its life all at once
• Esthetic concerns layered over all of the above

No two of these lists look alike, which is exactly the point. Complex care isn't a product you order. It's a diagnostic process that produces a plan specific to one mouth.

Why the mouth got here matters more than what to fix first

Here is the pattern we care most about interrupting: a tooth breaks, it gets repaired, and two years later a different tooth breaks — or the same one does. Each repair was reasonable on its own. But nobody asked why teeth in this mouth keep breaking.

Dentistry fails for reasons: a bite that overloads certain teeth, grinding the patient doesn't know about, acid quietly softening enamel, gum disease undermining foundations, or old restorations that left too little natural tooth behind. If those causes are still active, new dentistry inherits the same conditions that destroyed the old dentistry — usually on an accelerated schedule, because each repair cycle removes more tooth structure.

Rebuilding a mouth without understanding why it broke down is how you end up rebuilding it twice.

This is why our evaluation spends as much time on causes as on damage. It's also why the answer to "what would you do about this tooth?" is sometimes "let me first understand what's happening to all of them." We've written more about this pattern in Why Dental Work Fails — and How to Make It Last and The Mouth Is a Hostile Environment.

The four questions we answer before recommending anything

1. Is disease still active?

Decay and gum disease are infections, and you don't build on top of an active infection. Periodontal measurements, decay risk, and the health of root canal-treated teeth get established first — because they determine which teeth are worth investing in at all. Where gum treatment is needed, it comes before restorative work, not after. Our guide to gum disease and when a specialist is needed covers this in more depth.

2. What is each tooth's honest prognosis?

Every tooth in a complex plan gets its own evaluation: how much sound structure remains, where the fractures are, what the roots and bone look like, how many times it has already been repaired. Some teeth are solid. Some are restorable with the right approach. Some look salvageable but carry a poor long-term prognosis — and putting an expensive restoration on a tooth that's likely to fail is a decision you should get to make knowingly, not discover later. The save-the-tooth-or-replace-it decision deserves its own discussion, and we've given it one.

3. Is the bite stable?

The bite is the force system every restoration lives inside. If teeth are worn flat, if back-tooth support has been lost, or if the jaw closes somewhere different from where the teeth want to meet, new crowns built to the current bite inherit the current problem. Sometimes the bite is fine and this step is quick. Sometimes it's the entire case. Our guides on bite collapse, tooth wear, and finding your true bite explain how we evaluate this.

4. What do you actually want?

Two patients with identical X-rays can have different right answers. One wants the most durable result available and is prepared to phase it over two years. Another wants the most conservative path that keeps them comfortable and out of trouble. Both are legitimate. A plan that ignores what the patient values isn't a plan — it's a quote. This is also where honest conversations about budget, time, and treatment burden belong: at the beginning, not after the work has started.

If you want to see how these four questions get scored systematically, our dental risk assessment guide walks through the framework we use.

Three honest outcomes of a complex evaluation

Patients sometimes assume that a comprehensive evaluation is the front door to an enormous treatment plan. Here is what actually comes out of ours:

All three are real outcomes we deliver regularly. If every evaluation at a practice ends in the third column, that tells you something about the practice — a point we make at more length in our guide to advocating for yourself at the dentist.

How treatment is sequenced when reconstruction is warranted

When a mouth does need extensive work, the order is not negotiable, because each stage protects the investment made in the next:

• Stabilize disease. Gum health established, active decay controlled, teeth with hopeless prognosis addressed. Nothing durable gets built during this phase — and nothing durable should.
• Verify the foundation. The bite is evaluated and, where necessary, tested — sometimes with a splint or provisional restorations — before final work is made. If vertical dimension needs to change, this is where we prove the new position is comfortable. See how deprogramming works.
• Restore deliberately. Final crowns, onlays, implants, or combinations — designed digitally, sequenced so early work doesn't have to be redone to accommodate later work. Where implants are involved, planning starts from the final tooth position, not the available bone: how implants are really planned.

Phasing is normal. Many of our reconstruction patients spread treatment over one to three years, in an order designed so the mouth is stable and comfortable at every intermediate point. What makes phasing safe is that all the phases belong to one plan — for more on when a full rebuild is and isn't warranted, see our full-mouth reconstruction page.

Who does this work at MSD

MSD Dental Studio is an independent, doctor-owned practice on N University Drive in Coral Springs. Complex restorative cases here are planned jointly by Dr. Matthew Dillon and Dr. Shantall Di Loreto — two dentists, one coordinated plan, which matters most in exactly these cases.

Dr. Dillon is a general dentist with advanced continuing education in restorative, implant, and comprehensive dentistry, including training at the Kois Center and a Mastership in the Academy of General Dentistry (MAGD) — a recognition of more than 1,100 hours of continuing education held by fewer than 2% of general dentists. These are credentials and training, not a dental specialty; where a case genuinely calls for a specialist — complex periodontal surgery, certain endodontic retreatments — we say so and refer.

We focus on adult and teen patients (14+), and we regularly see patients from Parkland, Coconut Creek, Tamarac, Margate, and the surrounding North Broward communities who are looking for a second set of eyes on a larger dental problem.

Already holding someone else's treatment plan?

Many complex-care patients arrive with a treatment plan from another office — sometimes a very large one. We don't inherit other offices' plans; we perform our own evaluation and explain what we see. Sometimes we recommend less. Sometimes a different sequence. Sometimes we agree completely, which is worth knowing before you commit. Our second-opinion evaluation exists for exactly this situation.

Where to go deeper

Complex care touches many decisions. These doctor-written guides cover the ones patients ask about most:

• Why Dental Work Fails — and How to Make It LastThe honest reasons crowns and fillings fail, and what durable dentistry requires.
• Dental Risk Assessment: Know Your Risk FirstHow a modern exam scores periodontal, biomechanical, functional, and esthetic risk.
• Bite Collapse: Why Teeth Shift and Chip With AgeHow lost back-tooth support lowers the bite and overloads the front teeth.
• Save the Tooth or Replace It?How the decision is actually made — structure, prognosis, and strategic value.
• How Dental Implants Are Really PlannedWhy planning starts from the final tooth, not the available bone.
• Full-Mouth ReconstructionWho actually needs a full rebuild, who doesn't, and how we decide.
• When Multiple Crowns Are RecommendedHow to evaluate a multi-crown plan — tooth by tooth, phased or together.
• Multiple Missing Teeth: How Dentists ChoosePartials, bridges, implants, full-arch — how the field actually narrows.
• Worn-Down Teeth TreatmentWhy the cause of wear is diagnosed before anything is rebuilt.
