Dentists use dental dams as a barrier to isolate specific teeth during certain dental procedures.
You can find more information on our web, so please take a look.
The dental dam acts as a barrier to prevent blood and saliva from contaminating the isolated area. This helps with visibility, and access for the dentist and assistant, allowing them to keep a clean dry working field.
Dental dams are commonly used during procedures such as fillings and root canals, and by using a dental dam, dentists can ensure a more efficient and effective dental procedure and promote patient comfort and safety.
Infection Control: Dental dams act as a barrier, preventing the spread of saliva and oral bacteria between the patient's mouth and the treated area, reducing the risk of cross-contamination and infection.
Isolation: They isolate the tooth or teeth being worked on, providing a clear working field for the dentist by keeping the surrounding area dry and visible.
Protection: Dental dams shield soft tissues like gums, cheeks, and tongue from accidental contact with dental instruments, minimizing potential injuries during procedures.
Enhanced Visibility: By isolating the tooth, dental dams enhance visibility, allowing better access and precise treatment, especially during procedures like root canals and fillings.
Patient Comfort: They can improve patient comfort by preventing the accumulation of excess saliva and debris in the mouth during treatments, reducing the need for frequent interruptions.
Chemical Protection: Dental dams can protect the soft tissues from any chemicals or materials used during dental procedures, ensuring these substances don’t come into contact with other parts of the mouth such as their oral mucosa.
Preventive Measure: Using dental dams can help prevent the inhalation or ingestion of small dental materials or instruments by the patient.
Efficiency: They facilitate a more efficient dental procedure by aiding in moisture control and maintaining a clean, dry area for the dentist to work on.
Safety: Dental dams are a safety measure for both the patient and the dental practitioner, reducing the risk of accidental injury or exposure to infectious agents.
Patient Education: They serve as a visual aid, allowing dentists to demonstrate specific dental procedures to patients by isolating the treated area.
These benefits collectively contribute to maintaining a safer, more controlled, and efficient dental practice.
While dental dams have several benefits in dentistry, there are also some disadvantages associated with their use:
In the event of a latex allergy, alternative materials such as nitrile or polyisoprene dental dams can be used.
A dental dam may not be necessary for every procedure, but it is highly recommended for root canal treatment!
Root canal treatments involve the use of materials, irrigants and contaminants that should not be ingested by your patient. A properly placed dental dam ensures that your patient does not taste, or swallow anything during the procedure.
The dental dam is important for maintaining a sterile environment for the tooth in addition to preventing water, debris, and even cleaning tools or anything else from going down your patients throat.
The placement of a dental dam or rubber dam should not cause significant discomfort or pain as the patient is usually anesthetized during the procedure. Your patient however may feel some noticeable pressure when the dental dam clamp is being placed over the tooth to hold the dam in place. If placed correctly there should be no pain or pinching.
Dental dams are made from soft flexible materials such as latex, neoprene, or polyisoprene, and can come in different scents for patient comfort.
When applied correctly using the proper clamps for your specific use, dental dams are a great tool to use in dentistry. Not only to protect your patient but increase productivity for the dentist. With a rubber dam, the working field remains dry and isolated, reducing the need for cotton isolation, and reducing the risk for saliva contamination that could lead to treatment failure.
The components of dental dam equipment typically include the following:
Dental dam: The dental dam, also known as a rubber dam, is the key component of the equipment and is used to isolate the tooth or area being worked on during a dental procedure.
Dam clamps: Dam clamps are used to secure the dental dam in place during a dental procedure. They are designed to clamp onto the tooth, holding the dam securely in place.
Dental dam frame:The dam frame is used to hold the dental dam during the procedure, allowing an open field view of the area to be treated. Dam frames can be made of plastic, or metal, and some dams even have frames build in.
Dental dam punches:A dental dam punch is a tool used to create holes in the dental dam to easily place the dam over the tooth or teeth being worked on.
Dental Dam Forcep: The dam forcep is a tool designed to easily pick up and place the dental dam clamp over the tooth safely and with ease.
These are the basic components of dental dam equipment, and the specific components used will depend on the type of procedure being performed and the preferences of the dentist.

Dental dams are typically made from latex or latex-free materials.
Latex dental dams are made from natural rubber latex and for many years were the most common type of dental dam used in dentistry.
Latex-free dental dams are made from synthetic materials such as nitrile, neoprene, or polyisoprene.
With advancements in dental dam materials have notably addressed concerns regarding latex allergies while enhancing overall patient experience. Non-latex alternatives like polyisoprene and nitrile have emerged, providing viable options for those allergic to latex. These materials offer improved flexibility, thinner designs, and customizable sizes and shapes, catering to diverse patient needs.
In addition, flavored variations aim to enhance comfort during procedures. Biodegradable options contribute to environmental sustainability, and ongoing research is focused on developing allergen-free materials to minimize reactions in sensitive patients.
Combination of innovative application methods, improved retention mechanisms, and the exploration of new materials reflect the evolution of dental dams, ensuring increased comfort, safety, and efficacy in dental practices.
In summary, dental dams act as crucial barriers in dentistry, isolating specific teeth during procedures like fillings and root canals. They prevent contamination, enhancing visibility, access, and safety for both dentists and patients.
Despite their benefits, challenges can present themselves, including potential discomfort, placement difficulties, and allergic reactions in some patients.
However, advancements in materials and technology, including non-latex alternatives and improved designs, strive to overcome these challenges, promising increased efficiency, patient comfort, and safety in dental practices.

When you have an endodontic procedure, and the practitioner applies a dental dam used in dentistry to your mouth, you benefit from a decades’ old method of protection for you and the dental professional. This small piece of material has numerous advantages when used correctly.
In fact, in , the American Association of Endodontists put out its official position statement that dental dams should be part of all practitioners’ standard care levels. Using a dental dam, the endodontist creates a healthier clinical experience for both you and the practitioner.
In , Dr. Sanford Barnum introduced the first rubber sheet to cover a patient’s mouth during a dental procedure. Many people cannot believe it is over a century old, since they are just now experiencing the dental dam at recent dental appointments. Since Dr. Barnum created this device, dentists have used it to create a cleaner environment for working on their patients’ teeth. For non-surgical procedures, the dental dam has provided the easiest, lowest-cost method for isolating teeth and protecting the patient and dental professional. Commonly, endodontists use these dams for root canal therapy and similar procedures that benefit from tooth isolation. Dentists may occasionally use them for inserting fillings, too.
Construction of the dental dam may be either latex or non-latex. Some dental professionals may use latex for general use, and non-latex dental dams available for patients with allergies. In fact, here at Ballantyne Endo, we are a latex-free office to make sure we can accommodate all patients who need us!
The endodontist will use several instruments to prepare and place the dental dam used in dentistry in your mouth before the procedure. First, they will look at the tooth or teeth they need to treat to determine the holes’ size to create in the material.
Next, they will cut a hole or holes in the rubber to accommodate your teeth. They will then place the holes over the teeth and hold the dam in place with one or more clamps. Dr. Chopra likes to call it a “ring around the tooth.”
They will use a frame to stretch the dental dam over your mouth and lips, depending on its size and placement. This frame provides the required tension while it keeps the edges of the material from moving.
Dental dams vary in colors depending on the procedure and the practitioner’s preferences. For instance, some dentists prefer to use brightly colored dams to increase light in the area. Others choose to use dark materials, so the tooth or teeth stand out better. After the procedure ends, the practitioner will remove the frame, clamps, and dam before you can leave.
Dental dams are safe pieces of equipment used by dentists and endodontists. If your practitioner tells you that you will have one, rest assured that the process is not only safe but increases your level of protection.
When you have a dental dam in place, you will breathe through your mouth around the material’s sides and nose. If you have latex allergies, let the practitioner know to ensure that you get a non-latex dental dam. You will be more comfortable during and after the procedure by having a nonreactive rubber dam.
The majority of dental patients approve of their dentists using rubber dams. When dental practitioners have experience in quickly placing the dental dam, even patients anxious about using these devices feel more at ease. One of the most “relieving” effects is that the dam keeps water from going down your throat. This helps eliminate that “drowning feeling” you get when you are at the dentist. Proper communication and patient education are also important for recognizing how safe and beneficial dental dams.
A dental dam used in dentistry offers a myriad of benefits for practitioners and patients. Below are some of the advantages of dental dam use:
Your mouth has bacteria in it, and when an endodontist performs a root canal, you need protection from those germs naturally in your mouth. A dental dam isolates the tooth from the bacteria in your mouth, which reduces the chances of an infection in your treated tooth. The last thing you want to do is re-infect the tooth while you are trying to disinfect it. Plus, any bacteria released during root canal therapy stays out of your mouth.
Using a dental dam can protect practitioners from excessive exposure to saliva or blood from patients’ mouths. By covering the mouth and lips, the dam protects patients from getting cut by dental instruments. With a lower chance of bleeding and a covering over the mouth to prevent aerosol spray from saliva, dental dams prevent spreading contagious diseases from patients to practitioners.
With the mouth completely covered, the patient cannot aspirate any dental tools or tooth debris. Therefore, the patient has a more comfortable, safer experience.
Reducing bleeding chances is another way that dental dams protect both patients and practitioners. As noted, dental professionals can stay healthier. Patients, too, benefit from a reduced chance of bleeding when they have dental dams used on them. The dam’s rubber protects the lips, gums, and mouth tissues from scrapes, nicks, or cuts that could happen if the patient didn’t have a protective covering over their mouth.
Isolating specific teeth for a procedure ensures that dentists have a clean, dry area to work. Since the frame of the dental dam also holds the mouth open, more light reaches the worksite. With better light and dryer conditions, dental products such as fillings can set better. Additionally, the dental practitioner does not have to worry about saliva or oral debris impeding their work.
We at Ballantyne Endodontics commit to keeping our patients and staff safe during all procedures. Part of our safety standards includes applying a dental dam used in dentistry to each patient. We continue to use this standard as part of our procedures to prevent the spread of COVID-19. When you think about it, the rubber dam serves as a mask while your mouth is open in the dental chair.
