Root Canal Treatment in Richmond, TX
Care for a tooth when the nerve inside needs attention.
A root canal treats infection or inflammation inside a tooth so the tooth can often stay in place. At our Richmond office, Dr. Wei looks at the tooth first, explains what he finds, and recommends treatment here or with an endodontist when a specialist is the better fit. Convenient for patients from Katy and Fulshear.
Treatment for the tissue inside the tooth
Every tooth has a small inner space that holds soft tissue called the pulp — nerves and blood vessels that helped the tooth develop. When that tissue becomes badly inflamed or infected, often from deep decay, a crack, or an injury, the tooth can hurt, stay sensitive, or quietly develop a problem that shows up on an X-ray.
Root canal treatment removes the affected pulp, cleans and shapes the canals inside the root, and seals them so bacteria have a harder time returning. The tooth is then restored, often with a filling or a crown, so it can keep working in your bite. It is a way to keep a natural tooth when that is still a reasonable goal — not a guarantee that every tooth can be saved.
Signs you may need a root canal
These are reasons to come in, not a diagnosis. Tooth pain has more than one cause, and some teeth that need this treatment barely hurt at all.
-
Pain that lingers
A toothache that does not settle, or pain when you bite, is worth an exam. So is cold or heat that keeps hurting after the drink is gone.
-
Swelling or a gum bump
Swelling near a tooth, or a small pimple on the gum, can mean infection is draining from the root. That needs to be looked at even if the pain comes and goes.
-
Deep decay or a crack
A cavity or fracture that reaches the pulp can irritate the nerve. A filling is sometimes enough. When it is not, we will say so.
-
A finding on an X-ray
Infection at the tip of a root can show up on an image before it becomes obvious in the mirror. That is one reason exams matter even when nothing hurts.
-
A tooth that changed color
A single tooth that darkens after an injury can mean the pulp has been damaged. Color alone does not decide the treatment.
-
Pain that woke you up
Sudden, severe pain is a common reason for an emergency visit. Call us and we will help you sort out how soon you should be seen.
From the exam to a sealed tooth
Not every visit follows the same path. Some teeth are treated in one appointment. Others need more than one, or a referral, depending on infection, anatomy, and how comfortably the area can be numbed.
-
Exam and imaging
We look at the tooth, test it when useful, and take X-rays so the recommendation is based on more than the pain
-
A clear plan
You hear whether a root canal makes sense, what restoring the tooth may involve, and whether a specialist is a better setting
-
Numbing and cleaning
The area is numbed. The inflamed or infected tissue is removed and the canals are cleaned, disinfected, and shaped
-
Sealing
The canals are filled and sealed. A temporary or permanent filling closes the opening in the tooth
-
Restoring the tooth
Many back teeth need a crown afterward so the remaining tooth does not crack. We plan that before treatment starts
Root canal treatment and extraction solve different problems
Keeping a restorable tooth is usually worth discussing before removing it. Removal is the clearer choice when the tooth cannot be rebuilt with a predictable result.
-
When a root canal is considered
The pulp is inflamed or infected, and enough healthy tooth remains to clean, seal, and restore it. You keep the root in the bone, which helps hold the space in your bite. A crown is often part of that plan, especially for molars.
-
When extraction is considered
The tooth is split too far, broken below a level we can restore, or too compromised for a root canal to be predictable. A tooth extraction can then be the healthier step, followed by a conversation about leaving the space, a bridge, a denture, or an implant.
Dr. Wei will tell you if saving the tooth is realistic. If it is not, you will hear that before anything is scheduled.
What happens after a root canal
The tooth is usually sore to bite on for a few days. That tenderness is common while the surrounding ligament settles. Severe swelling, a bite that suddenly feels high, or pain that keeps building are reasons to call rather than wait.
The opening in the tooth needs a lasting restoration. A filling may be enough for a smaller front tooth. Back teeth, and teeth that were already cracked or heavily filled, often need a crown so they do not fracture later. If a same-day crown is a good fit for that tooth, we will say so. If a lab-made crown or a different restoration makes more sense, that is the recommendation.
A treated tooth still needs normal care: brushing, flossing, and checkups. It can still decay, and the seal can be disturbed by a new crack or leakage.
When a referral to an endodontist may be appropriate
Sunstone Dental is a general practice. Dr. Wei evaluates root canal needs as part of general dentistry, and he does not treat every case in the office. Some teeth are straightforward. Others have curved or calcified canals, a previous root canal that needs retreatment, a complicated infection, or anatomy that is better handled with the equipment and focus of an endodontist.
If a specialist is the better setting, you will leave with a clear reason and a referral — not a vague suggestion to “see someone.” If treatment here is appropriate, you will know what it involves, what restoring the tooth may add, and what we are not promising.
Tooth pain is not automatically a root canal. The exam decides whether the next step is a filling, a crown, root canal treatment, an extraction, medication, or a referral.
A referral is more likely when
- The canals are unusually curved, narrow, or hard to find
- The tooth has already had root canal treatment and still has a problem
- A separated instrument, a complex crack, or unusual anatomy changes the plan
- Swelling or infection makes the case less predictable in a general office
- You would simply rather be treated by a root canal specialist
Why root canals sometimes fail
A root canal can quiet a tooth and keep it for years. It can also need attention later. Failure usually means bacteria found a way back in, or the tooth itself broke — not that the idea of saving a tooth was wrong.
Common reasons include a canal that was missed, a seal that leaked, new decay under a filling or crown, or a crack that was not visible at the first visit. Waiting a long time to place the final restoration can also leave the tooth vulnerable. None of that means every treated tooth is fragile. It means the result depends on the tooth, the restoration on top, and follow-up.
If a tooth that already had a root canal starts to hurt, swell, or look different on an X-ray, the next step is an evaluation — retreatment, a different restoration, a specialist visit, or removal. Dr. Wei talks through that decision in the video.

Common Questions About Root Canal Treatment
How much does a root canal usually cost?
There isn’t one fee that fits every tooth. A front tooth with a single canal is a different visit from a molar with several canals, and the restoration afterward — a filling or a crown — is usually planned separately. Insurance benefits, whether a specialist is involved, and any current offer can change what you pay.
After the exam, you’ll get a written estimate before treatment is scheduled. If cost is part of the decision, say so. We can talk through timing, insurance, and the membership plan for patients without dental insurance.
How are bacteria cleaned out of the tooth?
The canals are cleaned mechanically and rinsed with a disinfecting solution, then dried and sealed so bacteria are less able to recolonize the space. The seal, and the filling or crown on top, matter as much as the rinse. Medicine inside the tooth is not a substitute for either one.
Which solution is used, and whether medicine is left in the canal between visits, depends on the infection and the tooth. That is a clinical choice made at the visit, not a home remedy.
Should I see a general dentist or an endodontist?
Start with an exam. A general dentist can diagnose the problem and treat many root canals. An endodontist is a specialist who spends their practice on this treatment and is the right referral for canals that are hard to find, teeth that have already been treated, or infections that are less straightforward.
At Sunstone, Dr. Wei makes that call with you. Being treated in a general office is appropriate for some teeth. Being referred is appropriate for others. Neither choice is a comment on how serious you are about the tooth.
When is it too late to avoid a root canal?
A root canal is avoided when decay or a crack is treated before it reaches the pulp — often with a filling or a crown. Once the pulp is infected or has died, cleaning the inside of the tooth, or removing the tooth, is what treats it. Antibiotics do not replace that.
It can also be too late to save the tooth at all, if there is not enough structure left to restore or the root is fractured. That is when we talk about extraction instead of urging a root canal that is unlikely to hold. An exam and an X-ray are how we tell those situations apart.
