The Ellicott City Smiles team jumping for joy outside the office, under the blue SMILES sign on Baltimore National Pike.

Specialists under one roof, in Ellicott City.

A periodontist, a prosthodontist, an oral surgeon, an endodontist and a dental anesthesiologist work alongside our general dentists on Baltimore National Pike, so almost nothing has to be referred across town.

Our story & mission

It is frustrating to get comfortable at a dental office, then be sent somewhere else the moment you need something special. So here the specialists come to you: gums, implants, dentures, root canals and sedation, all down one hallway.

Mercury-free since 1995, and built on one idea: we do not just treat teeth here, we treat people.

Sedation dentistry

Nervous? There are four ways to help.

We are a State of Maryland Certified IV Sedation Facility, one of only a handful of practices in the area to offer IV sedation, with a dental anesthesiologist on the team. The level matches how you feel.

A black leather treatment chair in one of the operatories.
01

Nitrous oxide

For mild nerves, a strong gag reflex, or a busy day.

Breathed through a small nasal mask. Within a minute you feel warm and relaxed, and it wears off almost as soon as the mask comes off. Gentle enough for children.

A soft armchair in the waiting room.
02

Oral conscious sedation

For moderate to severe anxiety, or longer treatment.

A prescribed pill, taken about an hour before. You stay awake and can answer questions, but you likely will not remember much. Someone needs to drive you.

Dr. Monica Tiu, the practice's dental anesthesiologist, smiling.
03

IV sedation

For extreme fear, or long and complex procedures.

Given through a vein, it works within minutes, and the level can be adjusted as you go. Most people recall little or nothing of the procedure afterwards.

A treatment room, with a screen above the chair.
04

General anesthesia

For patients who cannot sit comfortably for long.

Delivered by a team trained for it and monitored closely the whole time. Someone must drive you home and stay with you while it wears off.

A few specialist treatments worth knowing.

All-On-4

A full arch of teeth held by four implants. For people who have lost jawbone, it can mean skipping bone grafting altogether.

PAOO

Periodontally accelerated osteogenic orthodontics. For bites too severe for Invisalign, it can cut time in braces in half.

Pat Allen Tunnel Technique

A gum graft placed inside a small tunnel rather than stitched on top, which gives the new tissue a better blood supply.

Implant failure & salvage

If an implant starts showing signs of failing, call right away. The team works to save it.

Dental implants

Planned in 3D. Placed and restored here.

A periodontist and a prosthodontist on staff, planning from a 3D scan taken in the office. You will not drive between offices, file multiple claims or pay multiple providers.

  1. Consultation, and any gum treatment, extraction or bone graft first
  2. Implant surgery, with your mouth numbed
  3. Three to six months while the implant fuses with the bone
  4. Your final crown, bridge or denture

Thousands of smiles, and they say so.

Three of the reviews our patients left, in their own words. Jay, Jacqueline and Tim tell their stories on our YouTube channel.

★★★★★
This is the best dental office I have ever been to. Great atmosphere, clean, friendly office staff, very accommodating and professional. They take the time out to explain things and give you options on how you would like to handle your treatment. I would recommend this practice to anyone! You guys are amazing thank you for all you have done for me! Leanna T.West Friendship, MD
★★★★★
The entire staff was so friendly and welcoming!! Courtney at the front desk was very professional and so helpful with my insurance issues. Dr Modarres took the time to explain everything to me. He was very patient and kind. Finally, my hygienist Sheyoka was amazing!! I haven't been to the dentist in three years and she made me feel so comfortable and at ease. I can't say enough great things about this office! Jessica F.Woodmark, MD
★★★★★
I have to have gum recession treated and Dr. Modarres was so nice and calming. He provided me with details about my procedure. I think it was Rachael at the front desk who was friendly and professional. She offered me the option to run a test claim for my procedure and gave me a rough estimate of what the cost would be. So far I am happy with the service I have received. Ashley B.Catonsville, MD

Common questions

What people ask before they book.

Do you take my insurance?

We are in network with Delta Dental, Cigna, Blue Cross Blue Shield and MetLife, and with other major PPO plans, so call and ask about yours. Even if we are out of network, we still file the claim for you and look for ways to make treatment more affordable.

I am terrified of the dentist. Can you help?

Yes, and you would not be the first. Nitrous oxide takes the edge off within a minute. Oral conscious sedation is a pill taken about an hour before. We are a State of Maryland Certified IV Sedation Facility, and Dr. Tiu, our dental anesthesiologist, can provide general anesthesia when it is needed.

Will I feel pain if I am sedated?

Along with the sedative, the area is numbed with a local anesthetic, so it is unlikely you will feel pain. Depending on the sedative, you may not remember much of the appointment at all.

Can you replace my missing teeth?

Absolutely. Dental implants replace the whole tooth, root to crown, and can keep working for more than 30 years. Our periodontist and prosthodontist complete the whole process here, and the first consultation is free.

Do I need metal braces to straighten my teeth?

No. Invisalign clear aligners are practically invisible and come out to eat. If your bite is too severe for Invisalign, PAOO accelerated orthodontics can cut time in braces in half.

What if I cannot afford treatment?

Tell us. We offer low- to no-interest financing through Cherry and CareCredit, special offers through the year, and our own VIP Savings Plan for $50 a person, a year. Rachel will help you build a plan that works for your budget.

How often should I see the dentist?

At least twice a year, at any age. Those visits are when we clean your teeth and catch decay, cavities and gum disease at the earliest stage.
