Hearing that you need a root canal can be highly intimidating. What is a root canal? It is the removal of the nerve supply from the tooth. Here, Dr Karina Gregg will describe the parts of a tooth and explain the reasons for a root canal and how it is done when you visit us in our San Marcos, CA office.

Your tooth is made up of many layers. The outside layer is called enamel and is made of minerals. The middle layer is dentin, which is also a calcified tissue, but less dense. The center of the tooth is called the pulp, and that hosts the nerves and blood vessels. A root canal is the removal and replacement of this center with a sterile filling.

A root canal is needed when an infection spreads to the center of the tooth. This can be from trauma (recent or previous), a cavity, a severe crack, or other compromise that causes nerve damage. An X-ray and examination are required to see if a root canal is needed. Symptoms may include but are not limited to pain, swelling, change in tooth color, and over-reaction to temperature change or pressure.

When it is time to begin, you’ll receive local anesthesia (via injection) to make you most comfortable. A rubber dam is used to isolate the tooth, while other equipment determines the nerve location and maintains a sterile working environment. All of the infected area is removed including the nerve tissue and blood vessels. Then, medicines are used to sterilize and alleviate any pain. Next is the placement of a filling material in the spot where the nerve used to be.

When your nerve and blood supply are taken away, the tooth is non-vital, or dead, and can become weak and fragile. If your tooth is badly decayed, a large portion of it will have to be removed. It is recommended to place a crown on the tooth to keep the enamel from breaking or falling apart. If you do not get a crown, you could eventually lose the tooth to more decay or infection. The tooth could also break off completely and you would have to have an extraction. The crown fits over the top of the tooth and secures it from breaking down.

A root canal saves the life of a tooth that would otherwise succumb to further infection and eventually extraction. Infection is the cause of most-needed root canals. If you are ever unsure what is happening at your appointment, don’t be afraid to ask questions so you understand the procedure completely.

It is common to experience dentine hypersensitivity, with symptoms ranging from moderate to severe. Why does it happen and how do you know if this sensitivity is something to be concerned about? The first step is to determine the cause.

The most common cause of the sensitivity is exposure of the dentin. Dentin is the layer immediately surrounding the nerve of the tooth. It is alive and usually covered by the gum tissue. When gum recession is present hypersensitivity is common. Other contributors to temporary tooth hypersensitivity include teeth whitening and dental procedures such as fillings, periodontal treatment, and braces placement or adjustment. These are temporary and should be of no concern.

Permanent hypersensitivity, however, may require treatment. To understand the cause of sustained hypersensitivity, let us explain the structure of dentin and why it serves as a ‘hot spot’.

The dentin contains a large numbers of pores or tubes that run from the outside of the tooth to the nerve in the center. When dentin tubes are exposed, there is a direct connection between the mouth and dental pulp, which houses the nerve and blood supply of the tooth. External stimuli, such as mechanical pressure (tooth grinding or clenching - bruising the ligaments holding the teeth in place), temperature changes, as well as chemical stimuli (sweet–sour) are transmitted to the pain-sensitive dental pulp and activate nerve endings. A short and sharp pain is the result. These external stimuli cause fluid movement in the open tube that is transmitted as pain sensations. Something needs to be placed into the dentin tube to plug it and stop this fluid movement.

The first step in doing something about dental hypersensitivity is to determine the cause; our professional team at San Elijo Dental can help you with this. Whether the sensitivity is due to exposed dentin or an underlying cause such as abscess or decay, corrective measures are needed. Contact us sooner rather than later so Dr Karina Gregg can reduce the sensitivity, and provide you with some relief!

Do you dread the dentist? Do you hate the sound of the drill, fear anesthesia or needles, and put off your regular checkups because you dread being told you will have to undergo dental procedures? Then drill-free air abrasion dentistry is for you. Air abrasion is a drill-free technique used by Dr Karina Gregg to remove tooth decay, prepare teeth for bonding, and remove old fillings and stains. It is particularly appropriate for young children or people with dental anxiety, because it is sound- and vibration-free. It allows the creation of a relaxing atmosphere, requires less anesthesia in many cases, and involves much less noise.

How does drill-free dentistry work?

Air abrasion is like a mini sandblaster; it sprays away decay-causing tartar and plaque. Tartar and plaque is removed by a fine stream of particles, comprised of silica, aluminum oxide, or a baking soda mixture, which is sprayed toward the tooth by compressed air or a gas in a dental hand-piece. The debris is then suctioned away.

Advantages of air abrasion dentistry

• Leaves more of the healthy tooth matter
• Reduces the risk of chipping or fracturing the tooth
• Generates no heat, sound, vibration, or pressure
• Reduces the need for anesthesia
• Is a relatively simple, quick procedure
• Allows treatment of multiple teeth in one visit
• Is a relatively dry procedure, which allows for easy placement of composite fillings

Drill-free dentistry can go a long way to easing your dental anxiety. To enter San Elijo Dental and not hear the high-pitched squealing of the drill is, in itself, a big plus. Then to know you will have to receive little or no anesthesia to have a cavity filled with air abrasion, and that this method will be a quiet, relatively pain-free procedure … can you imagine it?

Contact San Elijo Dental at our convenient San Marcos, CA office to see if air abrasion dentistry is right for you!

Perhaps you don't even know you grind your teeth. Maybe a spouse or loved one woke you up in the middle of the night and made you aware of what was happening.

For many people, teeth grinding is a habit and a mechanical reflex; when they’re awakened and informed they were grinding their teeth, they have no recollection of it at all. According to the American Dental Association, this is the nightly situation for roughly ten percent of Americans. From young children to the elderly, teeth grinding, known in the dental community as bruxism, is a serious concern.

Many people who grind their teeth in their sleep have no idea they're doing it. In fact, when they wake up in the morning they feel no jaw pain and their teeth are fine: if it hadn’t been for someone telling them about it, the teeth grinding would have gone unnoticed.

There are other people, however, who wake up with jaw pain, shoulder and neck pain, and headaches. Teeth grinding can cause a host of dental complications. From cracked teeth and receding gums to a misaligned jaw, teeth grinding is not something to take lightly.

Preventive measures are the key to combating bruxism, and a visit to San Elijo Dental can set you on the path to a healthy and safe night sleep.

The Reasons for Teeth Grinding

There are many reasons for teeth grinding. For some people, it’s a habit they acquired when they were a child and never grew out of. On the other hand, some research claims that the condition is related to stress, anxiety, or some other type of psychiatric issue.

Still other studies point to everything from poor muscle control or over-eating before bed to gastro-esophageal issues. However, the root cause of the teeth grinding is less important than identifying preventive measures against it.

Common solutions to teeth grinding include:

• Wearing a protective nightguard
• Stress management techniques
• Medications and muscle relaxers

When you make an appointment with Dr Karina Gregg at our San Marcos, CA office, we will assess your situation and determine what the best course of action is. Teeth grinding is a dental concern that can cause serious health issues down the road, so be sure to take preventive measures today.
