Prevention is easy!

Protecting your smile against decay, gum disease, and tooth erosion is easier and more affordable than treating damage after the fact. At First Dental Associates in Reading, Massachusetts, Nasrin Sadeghi, DMD, Medha Singh, DMD, BDS, MS, and the team promote healthy, beautiful smiles through preventive treatments, like teeth cleanings and oral cancer screenings. Call the office today or schedule an appointment online to learn more about the benefits of preventive dentistry.

What is preventive dentistry?

Preventive dentistry aims to ward off dental disease, decay, and other oral health concerns. The goal of preventive dentistry is to keep your teeth and gums healthy as you age rather than treating problems after they develop. At First Dental Associates, the team works directly with you to create an individualized care plan that addresses your unique needs. 

Why is preventive dentistry important?

Preventive dentistry is the foundation of all oral health care. Detecting dental concerns early can save you time, money, and discomfort on invasive and costly treatments. 

For example, brushing, flossing, following a healthy diet, and attending regular teeth cleanings can prevent cavities (tooth decay). Once decay develops, it creates a small hole in your tooth that grows over time and eats away at its natural structure. 

Early intervention with fillings can help preserve your tooth, but waiting too long may require more invasive treatment, like a dental crown or root canal therapy. Without responsive treatment, decay can even lead to tooth loss.

What does preventive dentistry include?

First Dental Associates offers multiple preventive treatments, such as:

Teeth cleanings and dental exams

Teeth cleanings and dental exams aim to maintain your oral health. A teeth cleaning involves removing plaque (sticky bacteria) from your teeth and gums, while a dental exam evaluates your teeth, gums, and surrounding tissues to check for abnormalities (gum disease, abnormal growths, tooth erosion, and more).

Oral cancer screenings

An oral cancer screening is a visual exam that checks for abnormal lesions, sores, and growths. If your dentist uncovers potentially cancerous tissue, they can take a biopsy for testing.

Fluoride varnish treatments

Fluoride is a natural mineral that strengthens teeth. After your teeth cleaning, the team may apply fluoride varnish to protect your smile.

Dental sealants

Sealants are protective coatings that provide a barrier between your teeth and cavity-causing bacteria.

Nightguards

A nightguard fits over your top or bottom teeth to stop them from gnashing together. The team may recommend a nightguard if you have bruxism (teeth grinding) or temporomandibular joint disorder (TMJ). The practice also offers mouthguards for sports and snoring appliances for sleep apnea.

Personal Experience

I was referred to First Dental Associates by a family friend and have been a patient for more than 5 years now. The team at First Dental makes a visit to the dentist a pleasurable experience. Upon entering the office, I am greeted by Carol at the front desk, whom always wears a smile and asks how my family is doing, creating the kind of personal experience that is hard to find these days. The hygienists are always so friendly, professional, and thorough with cleanings. Dr. Sadeghi, also very kind and professional, has completed flawless dental work for me from replacing fillings to administering my Invisalign treatment. The office is impeccably clean and the equipment is all new. If you are looking for a dentist in the Reading area, I highly recommend First Dental Associates.

Fantastic Team

This is a team of wonder women! Their kindness compassion and complete lack of judgment was a slice saving as the impeccable job that they did on my ex-partner's teeth. It was one of the worst situations they had seen and a very delicate situation they tended to with utmost care. Even fun! The relationship ended but my gratitude for them is eternal and hope more humans can be like them!

Years of Great Service!

I have been going here for years. Extremely professional, kind, empathetic, and always considerate. I've had 3 pain-free root canals...hard to believe. I had neglected my teeth for years because of a fear of dentists. (I had a WW2 Navy dentist as a kid....enough said). Dr Sadeghi and her staff always take the time to ensure you a pain-free experience. The bonus is her hands are very tiny ...you won't feel like you have 2 or 3 spoons in your mouth. The quality of her work is superb. I can assure you that you will be impressed...I always am!

I am very anxious going to the dentist even for just a cleaning. Doctor Sadeghi is very caring and gentle. She is very understanding of my apprehension. She performs all services at the pace I can handle. I can’t say enough about the team. They’re just fantastic. I have had the best care by not only the doctor but by every hygienist that has cleaned my teeth. I look forward to seeing Carol. I can’t believe how she remembers specifics about each patient.
