Root canal treatment in Houston’s Energy Corridor
955 Dairy Ashford Rd · 77079
The pain is what brings people in — the root canal is what takes it away. Dr. Rosario treats the tooth and restores it here at 955 Dairy Ashford, so saving a molar does not mean two practices and two sets of fees.

Saving the tooth you already have
What a root canal actually does
Inside every tooth there is a soft core — the pulp — carrying the nerve and blood supply. When decay reaches it, or a crack lets bacteria in, or an old filling has been sitting deep for years, that tissue becomes inflamed and then infected. That is the throbbing that keeps people awake, and it does not settle on its own. Antibiotics can quieten it for a week, but they cannot reach inside a tooth to fix it.
A root canal removes that damaged pulp, cleans and shapes the narrow canals running down each root, and seals them so bacteria cannot get back in. The outside of the tooth — the part you chew with and smile with — stays exactly where it is. Nothing is taken out of your jaw, nothing needs replacing, and you keep the tooth you were born with.
It has an old reputation for being an ordeal. In practice the treatment is done under local anesthetic and the thing most patients actually notice is that the pain they arrived with has gone. What we will always tell you honestly is when a tooth is too far gone to be worth saving — because a root canal on a tooth that fractures six months later helps nobody.
How you know the nerve is involved
Signs you may need a root canal
One of these on its own is worth an X-ray. Two or three together usually means the pulp is already inflamed, and the sooner it is dealt with the more of the tooth we can keep.
Sensitivity that lingers
A sip of something cold hurts, and the ache is still there thirty seconds later. Healthy sensitivity fades the moment the cold goes.
The clearest early sign
The clearest early sign
A sharp jolt on that one tooth when chewing, or when you press it. Often the first thing patients notice with a cracked tooth.
Often a crack
Throbbing that wakes you
Spontaneous pain with no trigger, worse lying down, radiating along the jaw or up towards the ear. This one rarely waits politely for Monday.
See us the same day
The tooth has darkened
A single tooth going grey or brown next to its neighbors usually means the pulp inside has died, sometimes years after a knock.
Same-day repair
A pimple on the gum
A small bump near the root that comes and goes, sometimes with a salty taste when it drains. That is an infection finding a way out.
Needs treating
Swelling in the face or gum
Puffiness around the tooth or in the cheek. Infection that is spreading needs attention today, not next week.
Urgent
Deep decay or a large old filling
Sometimes there are no symptoms at all and the X-ray shows the decay has already reached the pulp. Better found now than at 2am.
Found on X-ray
A cracked or heavily worn tooth
Cracks let bacteria travel into the pulp. Grinders and clenchers see this more often than anyone else.

Straight answers
What people believe, and what is true
Root canals carry more folklore than any other treatment in dentistry. Most of it dates from before anesthetic and rotary instruments were what they are now.
“A root canal is agony”
What is trueThe treatment is done under local anesthetic, the same way a filling is. The pain people associate with root canals is the toothache that sent them to the dentist in the first place — and the treatment is what stops it. Most patients tell us afterwards that the appointment was less eventful than they had braced for.
“Just pull it, it’s cheaper”
What is trueOn the day, yes. Over five years, rarely. A gap left in the back of the mouth lets the neighboring teeth drift and the opposing tooth over-erupt, and replacing the tooth later with an implant or a bridge costs several times more than saving it would have. Sometimes extraction is still the right call — but not because of the price on the day.
“Antibiotics will sort it out”
What is trueAntibiotics travel in the bloodstream, and the inside of a tooth has no blood supply left once the pulp has died. They can settle a swelling and buy a few days, which is sometimes exactly what is needed — but the infection comes back until the inside of the tooth is cleaned out.
“Root canals make you ill”
What is trueThis comes from a theory published in the 1920s that was investigated and discarded decades ago. It resurfaces online periodically. Root canal treatment is one of the most-studied procedures in dentistry and there is no credible evidence linking it to disease elsewhere in the body.
Start to finish
How the treatment runs
One or two appointments for the root canal itself, then a separate visit for the crown on back teeth. Here is the order and roughly how long each part takes.
Diagnosis and X-ray
One visit · about 30 minutes
We test the tooth to find out whether the pulp is inflamed, dying or already dead, and take an X-ray to see the roots and any infection at the tip. This is also where we tell you honestly whether the tooth is worth saving.
Numbing and isolation
Same visit
The tooth is numbed thoroughly — nothing starts until it is. A rubber dam is then placed over it, which keeps the tooth dry and stops anything reaching the back of your throat. It is the least glamorous part of the appointment and the one that most affects the result.
Cleaning and shaping the canals
60–90 minutes for most teeth
The damaged pulp is removed and each canal is cleaned along its full length and shaped so it can be sealed. A front tooth usually has one canal; a molar commonly has three or four, which is why molars take longer and cost more.
Sealing the canals
Same or second visit
The canals are filled with a rubbery material and sealer so bacteria cannot re-enter. Some teeth are finished in one appointment; where there is active infection, we sometimes dress the tooth and complete it at a second visit.
Rebuilding the tooth
Same visit as sealing
A treated tooth has had its inside hollowed out and is more brittle than it was. Front teeth can often be restored with a filling. Back teeth almost always need a crown, and skipping it is the most common reason a root-canalled tooth is lost later.
Crown and review
Two visits over a few weeks
Dr. Rosario takes the impression, fits the crown and checks the bite. We then review the tooth at your normal check-ups and X-ray it again after a while to confirm the infection at the root tip has healed.
Why the quote depends on the tooth
Front tooth, premolar or molar
A root canal is not one price, because it is not one job. The number of canals inside the tooth decides how long it takes and what it costs.

Afterwards
What to expect once it is done
General guidance for a straightforward case. Your own instructions come from Dr. Rosario on the day and take priority over anything here.
The original pain should be gone
The ache that brought you in usually stops the same day. What replaces it for two or three days is a duller tenderness when biting, because the ligament around the root has been worked on.
Chew on the other side until it is crowned
A tooth with a temporary filling in it is vulnerable. Keep hard and sticky food away from that side until the permanent restoration is fitted.
Ordinary pain relief is usually enough
Over-the-counter pain relief taken as directed handles most of it, and most people are back to normal within a couple of days. Numbness wears off over a few hours — do not chew until it has.
Do not put the crown off
This is the single most important thing on this page. A back tooth left under a temporary filling for months will eventually split, and a split root cannot be repaired — the tooth comes out, and the root canal was for nothing.
Clean it like any other tooth
A treated tooth still has gum around it and can still decay at the margins. Brushing, flossing and regular check-ups matter exactly as much as they did before.
How long it lasts
A properly treated and properly crowned tooth commonly lasts many years and often the rest of your life. The two things that shorten it are a delayed crown and a fracture.
Call us if any of this happens
.Pain that is getting worse rather than better after two or three days.
.Swelling of the gum or face that appears or increases after the appointment.
.Your bite feels high on that tooth — a quick adjustment usually settles it and it is a two-minute visit.
.The temporary filling has come out or the temporary crown has come off.
.A fever, or feeling generally unwell rather than just sore.
.Difficulty breathing or swallowing — do not wait for us, go to an emergency room or call 911.
There is no charge for calling to ask, and a bite adjustment or a re-cemented temporary is a short appointment.
Why patients choose us for root canals
Treated and crowned under one roof
A lot of practices do the root canal and send you elsewhere for the crown, or the other way round. That gap is where teeth get lost, because the temporary sits in place far longer than it should.
One practice, start to finish
Dr. Rosario does the root canal and the crown that protects it. Nobody is waiting on another office’s schedule, and the tooth is not left under a temporary for months.
Same-day appointments for pain
We keep emergency slots open six days a week. If the nerve is the problem, getting you comfortable is the first appointment, not the third.
We tell you when not to do it
A tooth with a split root or too little structure left is not worth a root canal, and we will say so and talk through the alternatives rather than treating it anyway.
Dr. Gandhi is down the corridor
If the honest answer turns out to be extraction and an implant, that is handled in the same building rather than referred across the city.
The cost in writing first
Front, premolar and molar are priced differently and the crown is separate. You are told the full figure before we begin, not after.
Sedation options
Root canals bring in a lot of anxious patients, usually because of what they have heard rather than what they have had. We will talk through the options with no pressure either way.
Saturday appointments
Open six days a week, so the treatment and the crown fitting do not both have to come out of your work week.
English and Spanish
Both dentists and the whole front-desk team work in both languages, including consent and aftercare instructions.
What it costs
Root canal cost in 77079
Two figures matter: the root canal itself and the crown that protects it afterwards. We publish both, because being quoted only the first one is how people get a surprise later.

Retreatment means removing the old filling material from canals that were sealed before, which takes longer than a first-time root canal. You will have the figure in writing before treatment starts.
Worth comparing
A molar root canal and crown on the membership plan comes to $1,798. Extracting that tooth and replacing it later with an implant and crown starts at $1,999 plus the extraction, and takes several months. Saving the tooth is usually both cheaper and faster — when the tooth can be saved.
Questions we get asked
Root canal FAQs
How much does a root canal cost in Houston?
On our in-house membership plan a root canal is $699 for a front tooth, $799 for a premolar and $999 for a molar, because a molar has three or four canals to clean rather than one. Back teeth also need a crown afterwards, which is $799, or $899 where a build-up is needed first. The emergency exam and X-rays are included on the plan, and you get the full figure in writing before anything starts.
Does a root canal hurt?
The treatment is done under local anesthetic, so you should feel pressure rather than pain — the same as having a filling. The pain people associate with root canals is the toothache that sent them to the dentist, and the treatment is what removes it. Afterwards the tooth is often tender to bite on for two or three days, which over-the-counter pain relief handles. Sedation options are available if the appointment itself is what worries you.

Do I really need a crown after a root canal?
On a back tooth, almost always. Cleaning out the inside of a tooth leaves it more brittle, and molars take the full chewing load. A crown holds the tooth together; without one, a split is likely eventually, and a split root cannot be repaired — the tooth has to come out and the root canal was wasted. Front teeth carry much less load and can often be restored with a filling instead.
Is it better to have a root canal or to pull the tooth?
On a back tooth, almost always. Cleaning out the inside of a tooth leaves it more brittle, and molars take the full chewing load. A crown holds the tooth together; without one, a split is likely eventually, and a split root cannot be repaired — the tooth has to come out and the root canal was wasted. Front teeth carry much less load and can often be restored with a filling instead.
What happens if I leave an infected tooth untreated?
The infection does not resolve on its own. It works its way out through the bone at the tip of the root, which is what forms an abscess or a pimple on the gum, and it can flare into facial swelling. Along the way the tooth usually becomes harder to save, so a treatment that would have kept it can turn into an extraction. If your face is swelling, or you have a fever, treat that as urgent rather than waiting.
Can a root canal fail, and what happens then?
Most treated teeth do well for many years, but a small proportion do develop trouble later — usually because a canal was unusually shaped, because bacteria found their way back in through a leaking restoration, or because the tooth fractured. The usual options are retreatment, where the old filling material is removed and the canals are cleaned again, or removal of the tooth. Retreatment takes longer than a first-time root canal, which is why it is quoted case by case.
Can I go back to work straight after a root canal?
Most people do. There is no sedation involved in a routine root canal, so you can drive yourself and go back to your day. Your lip and tongue will be numb for a few hours, so leave eating until the numbness has fully worn off, and chew on the other side until the permanent restoration is fitted.
Can I have a root canal while pregnant?
Yes — treating an active dental infection is generally considered safer than leaving it, and routine dental treatment during pregnancy is well established. X-rays are taken only where they are needed for the diagnosis, with appropriate shielding. Tell us you are pregnant and how far along when you book, so we can plan the appointment and anything we prescribe around it, and check with your physician if you would like to.
Why does my tooth still feel tender a few days later?
That is normal and it comes from the ligament around the root rather than from inside the tooth. It usually settles within a few days. What is not normal is pain that increases rather than decreases after day two or three, new swelling, or a bite that feels high on that tooth — call us for any of those, and a bite adjustment in particular is a two-minute appointment.
