Are you thinking of getting dental implants?

The first modern titanium dental implant was placed over 30 years ago by a Swedish orthopedic surgeon, Dr. Per Ingvar Branemark. Since implantsthen, they’ve only continued to grow in popularity and development. This restorative procedure rejuvenates and strengthens your smile. Thoroughly designed prosthetics replace your natural teeth. Your smile is a life-long investment, you shouldn’t be afraid to show it off. Dental implants give you the smile you deserve. Dr. David Rosen provides implant dentistry to patients in the Lexington, Northwest Boston, and the surrounding areas. Contact his office today to learn more.


Dental Implants

Dental implants are biocompatible fixtures surgically placed into the jawbone. Dental implants consist of several parts: a titanium post that's inserted into the jawbone, a screw that secures an abutment over the titanium post, and a crown matching the rest of your teeth.


The Implant Procedure at Your Lexington Periodontist

The procedure is straightforward.

  1. The titanium post is surgically inserted into your jaws to replace the missing tooth root. It provides stability and strength, preventing weakening and shrinkage of the jawbone.

  2. After inserting the titanium post, Dr. Rosen seals your gums and allows 3 to 6 months for osseointegration (a process of the post fusing to the rest of your jawbone) to occur.

  3. After healing is complete your Lexington dentist re-opens the area above the titanium post, inserts a screw, places an abutment above the screw, and finally secures a crown on top that matches the rest of your teeth.

Caring for Dental Implants

To take proper care of your dental implants, make sure you brush your teeth at least twice a day and floss daily. A change in diet may also be beneficial. Eating plenty of fruits and vegetables while avoiding sugary foods prevents the accumulation of plaque.


There are several advantages to dental implants:

  • They restore bite and chewing function.

  • Act as replacements for one or multiple teeth.

  • Complete your smile and set of teeth.

Face Your Dental Fears Once and for All with Help from Sedation Dentistry.

We know that not everyone loves visiting the dentist and we certainly don’t take it personally. While the goal of our Lexington, MA, sedation-dentistryperiodontist, Dr. David Rosen, is to make sure that you always have a comfortable and smooth visit, we understand that a lot of people are still dealing with dental anxiety. If this sounds like you, sedation dentistry may just end up being your best friend. Dr. Rosen proudly serves residents of Lexington, Northwest Boston, and the surrounding areas.

What Is Sedation Dentistry?

Sedation dentistry is a safe and effective way to get the proper care you need without dental anxiety. Patients of our periodontist Dr. Rosen are often coming in for restorative treatments and oral surgeries such as dental implants, and because of this, some patients may be a bit nervous. Luckily, Dr. Rosen offers a way to help you relax so that we can treat your smile and improve your oral health without stress.

What Are the Different Kinds of Sedation Dentistry?

The most common type of sedation dentistry is oral sedation, which comes in the form of prescription anti-anxiety medication such as Valium. You will come into the office to take this sedative about 30 minutes to one hour before your procedure.

The great thing about oral sedation is that we can choose the level of sedation you require based on the type of treatment you are receiving and your subsequent level of anxiety. While it will take the medication up to 45 minutes or so to fully kick in, the effects will last the length of your procedure. It’s common for patients to feel groggy after taking oral sedation, so it’s important that they are accompanied by a family member or friend who can transport you home.

Another type of sedation dentistry is inhalation sedation, during which we apply a gas mask over the nose. The mask provides a mix of oxygen and nitrous oxide, better known as “laughing gas”. Unlike oral sedation, which takes time to kick in, inhalation sedation will work immediately, allowing us to get to work right away. An additional benefit is that the effects wear off the minute the mask is removed.

What Procedures Can Be Performed Under Sedation Dentistry?

To help you feel more relaxed in the dentist’s chair, we can use sedation dentistry for just about any of the procedures we offer. This includes everything from dental implant placement to bone grafting to gum disease therapy. When scheduling your appointment, ask us if sedation dentistry could benefit you.

Tags: Gum Grafting  

Gum recession is an issue that can be repaired using gum grafting techniques. This important procedure can help protect your teeth from the symptoms and complications of gum recession and improve the appearance of your smile. Find out more about gum grafting surgery and what it can mean for you with Dr. David Rosen in Lexington, MA, serving residents of Lexington, Northwest Boston, and the surrounding areas.

What is gum grafting? 
Gum grafting is a procedure which focuses on treating receding gums. This somewhat common condition causes the gum tissue to pull away from the teeth, creating pockets. The process advances slowly and many people do not realize they have receding gums until their condition is serious. The process exposes the tooth’s root which can cause sensitivity and look unsightly.

Do I need gum grafting surgery? 
Gum recession is normally not obvious until it is in its later stages. However, if you have gums which pull slightly up from the teeth, you could have gum recession. Some other, sometimes more subtle symptoms of gum recession include:

  • bleeding gums while brushing or flossing
  • unexplained bad breath
  • loosened teeth
  • red, swollen gums
  • painful gums
  • exposed tooth roots

What can I expect from gum grafting treatment? 
Before performing the procedure, your periodontist will numb the treatment area to ensure you do not feel any discomfort or pain. Depending on the type of graft, your dentist will remove a small piece of tissue from the roof of the mouth, the connective tissue from underneath the tissue on the roof of the mouth, or gum tissue directly next to your graft area. They then cover the exposed tooth root and secure the new tissue in place. The procedure usually takes about an hour and requires only a short recovery time. During the healing process, your dentist will recommend eating soft foods and use a special mouthwash. You should also avoid brushing or flossing in that area until you are cleared to do so by your dentist.

Sedation DentistryHow sedation dentistry from your periodontist in Lexington can help you

If dental appointments make you uneasy, you are not alone. Many people suffer from a very real fear of dental appointments, but don’t be afraid! Sedation dentistry can help you have a virtually worry-free appointment. Dr. David Rosen in Lexington, MA, wants to share how sedation dentistry can help you. He proudly serves residents of Lexington, Northwest Boston, and the surrounding areas.

Dental anxiety and fear aren’t all in your head. In fact, dental fear produces some very real physical symptoms including a racing heartbeat, shortness of breath, sweating, and other symptoms. The truth is dental fear can make you procrastinate and not get necessary dental work completed, which can lead to problems with your smile and your general health.

When you choose sedation dentistry, you will enjoy important benefits like these:

  • A comfortable appointment
  • A relaxing experience
  • Getting more dental work completed in a shorter amount of time

Dr. Rosen offers several options, depending on the level of sedation you want to achieve. Consider:

  • Oral sedation taken as a pill; if you need to be mildly to moderately sedated, but are still able to respond to questions.
  • Intravenous sedation which is injected directly into a vein; the sedative effects of IV sedation are immediate and profound. You may not remember your appointment.

When you choose sedation dentistry, it is vitally important to bring someone with you who can drive you home after your appointment.

Tags: Crown Lengthening  

Find out if this surgical procedure could restore your damaged lengthening

There are many cosmetic and restorative benefits that come with crown lengthening. If you are embarrassed by your gummy smile and wish your smile was more proportional then our periodontist in Lexington, MA and serving Northwest Boston and the surrounding areas, Dr. David Rosen, can help with this procedure.

Besides improving the overall appearance and symmetry of your smile, our periodontal specialist here in Lexington, MA, might also recommend crown lengthening if there is a crack or fracture in a tooth that goes below the gum line or if there isn’t enough tooth to support a restoration like a dental crown or bridge. In these cases, crown lengthening can help reveal more of the tooth and to treat any damage immediately before the problem gets worse.

What goes into crown lengthening?

Before the procedure is performed we will take x-rays of your mouth and also discuss your detailed medical history. We will also need to perform a dental cleaning prior to your surgery.

The first thing that we will do is administer a local anesthesia to numb the area. The length of treatment will depend on how many teeth we need to treat. In some cases, only gum tissue is removed, but sometimes we have to remove both gum tissue and bone. We will make small incisions in the gums to pull them away from the teeth. By removing excess gum tissue we can often reveal as much of the tooth that’s needed either for cosmetic or restorative purposes. Once the gum tissue and/or bone have been removed, we will stitch up the gums.

We will provide you with thorough instructions on how to care for your smile while your mouth heals. In about a week to 10 days, you’ll come back into the office to have the stitches removed. During that time if you notice any of these signs of infection you must call us right away:

  • Bleeding that won’t stop
  • Severe or worsening pain that pain relievers can’t treat
  • Swelling or discharge from the gums
  • Swollen lymph nodes under the jaws

Call our periodontist in Lexington, MA and serving Northwest Boston and the surrounding areas about whether crown lengthening surgery is right for you.
