Stories i tell spell tales but this, this is an experience instead. Their flexibility and the great staff were my parting realities. I mean, the doctor is mellow, not rushed, the hygienist honest, no bluff, and the receptionist, well, memory sharp. This is my dentist going forward.

Patients seek a well-respected dentist in Smyrna for root canals

Image of Dentist for Root Canals Smyrna
Constant pain when chewing may be the symptom of a tooth infection. The pain may be caused by damage inside the pulp chamber. Infections can develop after trauma or due to improper oral hygiene habits. Regardless, root canals can be ideal for saving the affected teeth and providing pain relief. Patients will find root canal treatment in the hands of a well-respected dentist at Smyrna Dental & Headache Center. For years, Dr. David Lamothe has been saving teeth with root canals. Dr. Lamothe and his team provide affordable, comfortable, and convenient treatment.

It helps to understand the anatomy of the tooth. The interior of the tooth is comprised of blood vessels, nerves, and other tissues. A fracture or decay can lead to infection. Once a tooth is infected, the dental pulp begins to die. Then, the body’s inflammatory responses set in.

In addition to a toothache, there are multiple other signs of infection including tooth discoloration, an abscess, and gum tenderness or swelling. It is important to seek treatment immediately for a couple of reasons. One, Dr. Lamothe and his team can provide relief to a throbbing toothache. Two, the cost can vary based on the severity of the tooth infection. The longer patients wait, the more severe their infection can become.

Before a root canal, local anesthetic is used to numb the affected area. Next, the damaged portions of the tooth are removed and canals are cleaned, disinfected, shaped, and sealed. Then, the tooth is restored with a natural looking porcelain crown.

Are you looking for relief from a toothache or any other symptoms of an infection? The team at Smyrna Dental & Headache Center would be happy to help you. We recommend scheduling an appointment with Dr. Lamothe so he can evaluate the health of your mouth, teeth, and gums. He will listen to any concerns you have and answer your questions to ensure you feel comfortable about treatment. If root canal therapy is right for you, he will tailor a treatment plan to meet your individual and unique needs. Schedule an appointment by calling 678-374-3764.
