Featured Answer: How much does a root canal cost in Massachusetts?
A root canal in Massachusetts typically costs $700-$1,800 (current as of 2026), and the price depends on which tooth is treated — because the number of canals drives the work involved. After an exam and X-rays, we give you a transparent, written estimate.
| Tooth (canals) | Root canal fee | CDT code |
|---|---|---|
| Front tooth — incisor or canine (1 canal) | $700-$1,100 | D3310 |
| Premolar / bicuspid (1-2 canals) | $800-$1,300 | D3320 |
| Molar (3-4 canals) | $1,000-$1,800 | D3330 |
Most premolars and molars also need a crown afterward ($1,000-$1,800), so the all-in cost to fully restore a back tooth is often $1,700-$3,300. Dental PPOs usually cover 50-80% after your deductible, and we offer 0% financing through CareCredit and Cherry.

What a Root Canal Costs by Tooth Type (and Why)
Root canal fees aren't arbitrary — they track the number of canals inside the tooth, because every canal has to be individually located, cleaned, shaped, and sealed.
- Front teeth (incisors and canines) have a single canal, so they are the quickest and least expensive to treat (CDT code D3310).
- Premolars (bicuspids) usually have one or two canals (CDT code D3320).
- Molars typically have three or four canals — sometimes more — which is why they cost the most and take the longest (CDT code D3330).
This is the same reason molars take more chair time than front teeth; we break down the timing in our guide on how long a root canal takes. If you've heard that the procedure itself is something to dread, our root canal myths and pain relief guide covers how modern anesthesia and rotary instruments keep treatment comfortable.
Don't Forget the Crown: The Other Half of the Cost
For premolars and molars, the published root canal fee is only part of the picture. After the nerve is removed, a back tooth becomes more brittle and needs a crown to protect it from cracking under chewing force. A crown adds roughly $1,000-$1,800 and is placed at a separate appointment once the tooth has settled.
Front teeth are different — because they take less force, they can sometimes be restored with a bonded filling instead of a crown, which keeps the total cost down. At your consultation, Dr. Fatima will tell you up front whether your tooth needs a crown so there are no surprises on the estimate.
What Drives Root Canal Cost Up or Down
Several factors move the final number within (or beyond) the ranges above:
- First-time treatment vs. retreatment. Redoing a previously treated tooth (CDT codes D3346-D3348) is more complex and costs more than an initial root canal.
- General dentist vs. endodontist. A specialist (endodontist) typically charges more than a general dentist. Dr. Fatima completes many root canals in-house in Marlborough, and refers genuinely complex cases when that serves the tooth best.
- Imaging. Difficult anatomy may call for a 3D CBCT scan to map the canals accurately.
- Tooth complexity. Curved or calcified canals, extra canals, or a tooth with existing infection take more time.
- Geography. Orthodontic and endodontic fees in downtown Boston and Back Bay commonly run 10-20% higher than MetroWest. Patients from Framingham, Shrewsbury, Northborough, and Southborough come to our Marlborough office for that reason.
Does Dental Insurance Cover Root Canals?
Most PPO dental plans treat a root canal as a basic or major service and pay 50-80% after your deductible, up to your plan's annual maximum. Two things to check before you commit:
- Waiting period. Some plans impose a 6-12 month wait before covering major work — see our breakdown of dental insurance waiting periods.
- Annual maximum. If a root canal and crown together approach your yearly cap, splitting treatment across two benefit years (December and January) can stretch your coverage.
We are in-network with most major PPOs — Delta Dental, Blue Cross Blue Shield, MetLife, Cigna, Aetna, Guardian, Humana, UnitedHealthcare, and United Concordia — verify your benefits, and file the claim for you. Details are on our insurance and financing page.
Root Canal vs. Extraction and Implant: The Real Cost Comparison
When a tooth is painful, it's tempting to think pulling it is the cheaper path. It usually isn't:
- Root canal + crown: about $1,700-$3,300, keeps your natural tooth, and is finished in a couple of visits.
- Extraction + implant + crown: about $3,000-$6,000, takes several months of healing, and means losing the natural tooth.
Saving a restorable tooth with root canal therapy is typically the more economical and conservative choice. We compare the all-in numbers in our dental implant cost guide so you can see both paths side by side. If a tooth truly can't be saved, we'll walk you through tooth replacement options honestly.

Frequently Asked Questions About Root Canal Costs
How much does a root canal cost without insurance in Massachusetts? Without insurance, expect roughly $700-$1,100 for a front tooth, $800-$1,300 for a premolar, and $1,000-$1,800 for a molar at a general dentist; endodontist fees run higher. Most back teeth also need a crown afterward, adding $1,000-$1,800. At Innova Smiles we give you a written estimate before treatment and offer 0% financing so the cost is spread over monthly payments.
Does dental insurance cover root canals? Most PPO dental plans cover root canals as a basic or major service, typically paying 50-80% after your deductible — subject to your annual maximum and any waiting period for major work. Coverage varies by plan, so we verify your benefits and file the claim for you.
Is a root canal cheaper than pulling the tooth and getting an implant? Usually, yes. A root canal plus crown commonly totals about $1,700-$3,300 and saves your natural tooth, while an extraction followed by an implant and crown often runs $3,000-$6,000 and takes several months. Saving the natural tooth is typically the more cost-effective and conservative option when the tooth is restorable.
Why does a molar root canal cost more than a front tooth? Cost tracks the number of canals. A front tooth usually has one canal, a premolar one or two, and a molar three or four. More canals mean more cleaning, shaping, and filling time, which is why molars cost more and take longer.
Do I need a crown after a root canal, and how much does it add? Back teeth almost always need a crown after a root canal because the tooth becomes more brittle and takes heavy chewing force. A crown adds about $1,000-$1,800 and is placed at a separate appointment. Front teeth can sometimes be restored with a filling instead, which costs less.
