The difference between canker sores and cold sores

Although canker sores are often confused with cold sores, there is a difference.

Canker sores occur inside the mouth, and cold sores usually occur outside the mouth.

Canker sores are small ulcers with a white or gray base and a red border. There can be one or more sores in the mouth. They are very common and often recur.

They usually heal in a week or two and rinsing with antimicrobial mouth rinses may help reduce the irritation.

Cold sores – also called fever blisters – are composed of groups of painful, fluid-filled blisters that often erupt around the lips and sometimes under the nose or chin.

Cold sores are usually caused by herpes virus type I and are very contagious. They usually heal in about a week.

Over-the-counter topical anesthetics can provide temporary relief and prescription antiviral drugs may reduce these kinds of viral infections.

Why cavities aren’t just for kids

Tooth decay or cavities result from destruction of the tooth enamel and can lead to a range of problems from toothache to bad breath.

Cavities occur when foods containing carbohydrates (sugars and starches) such as milk, sugared drinks, cakes or candy are frequently left on the teeth.

Bacteria that live in the mouth thrive on these foods, producing acids as a result. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay.

Many people associate cavities with children but the changes that occur with aging make cavities an adult problem, too.

Recession of the gums away from the teeth, combined with an increased incidence of gum disease, can expose tooth roots to plaque.

Tooth roots are covered with cementum, a softer tissue than enamel. They are susceptible to decay and are more sensitive to touch and to hot and cold. The majority of people over age 50 have tooth-root decay.

Decay around the edges of fillings is also common to older adults. As many of them did not benefit from fluoride and modern preventive dental care when they were younger, they often have a number of dental fillings.

Over the years, these fillings may weaken, fracture and leak around the edges.

Bacteria accumulate in these tiny crevices causing acid to build up which leads to decay.

You can help prevent tooth decay by following these tips:

– Brush twice a day with fluoride toothpaste
– Clean between your teeth daily with floss or interdental cleaner
– Eat nutritious and balanced meals and limit snacking

It’s also worth asking your dentist about supplemental fluoride, which strengthens your teeth, and about dental sealants, a plastic protective coating which is applied to the chewing surfaces of the back teeth to protect them from decay.

In addition, it’s important to visit your dentist regularly for professional cleanings and oral examination.

Different types of dentist and how they help your oral care

While many people see dentists as the single group of people who look after the health of your teeth and mouth, there are various specialist categories that help you in different ways.

The categorization of a dentist will depend on their education, training and experience.

Here are some of the main specialist areas of dentistry:

Endodontics: Concerned with the dental pulp – the part in the center of a tooth made up of living soft tissue and cells and root canal therapy

Oral and Maxillofacial Pathology: This deals with the identification, and management of diseases affecting the oral and maxillofacial regions

Oral and Maxillofacial Radiology: Deals with the production and interpretation of images and data produced by radiant energy that are used for the diagnosis and management of diseases, disorders and conditions of the oral and maxillofacial region

Oral and Maxillofacial Surgery: Diagnosis and surgical treatment of diseases, injuries and defects of the tissues including extractions, facial surgery and implants

Orthodontics and Dentofacial Orthopaedics: Mainly deals with diagnosis, prevention and treatment of misaligned teeth and modification of midface and mandibular growth

Pediatric Dentistry: Provides preventive and therapeutic oral health care for infants and children through adolescence.

Periodontics: Prevention, diagnosis and treatment of diseases of the supporting and surrounding tissues of the teeth and the maintenance of the health, function and esthetics of these structures and tissues. Most periodontist place implants

Prosthodontics: Diagnosis, treatment planning, rehabilitation and maintenance associated with missing or deficient teeth and/or oral and maxillofacial tissues. Includes dentures, bridges and the restoration of implants.

Plus, of course, general dentists provide everyday care and many specialist services to maintain your oral health.

How implants changed dentistry

Implants are one of the most important developments in dental care over recent years.

They have created opportunities that didn’t exist before for people to improve their dental health and create the smile they want.

Implants were discovered by Swedish scientist and orthopedic surgeon Dr. P.I. Brnemark and they have transformed the quality of life for people who have missing teeth.

The basis of a dental implant is a titanium rod about 1cm long. This is placed inside the jawbone and is designed to serve the same purpose as tooth roots.

Implants can either be used to replace lost teeth or to help keep dentures in place more securely.

One of the reasons implants have changed dental care so much is that, previously, there was often no other way to replace missing teeth permanently.

And there are many people who cannot tolerate removable dentures or don’t want to wear them for some other reason.

The introduction of implants had made a big change in their lives.

How medication and anesthesia can help make your visit to the dentist easier

Your dentist will do everything possible to make your visit as relaxed and comfortable as possible.

Depending on the treatment you are receiving, there are several medications available to help.

Some drugs control pain, some help you relax and others put you into a deep sleep during dental treatment.

The best approach will depend on the type of procedure being undertaken, your overall health – including any history of allergies – and the degree of anxiety you feel.

Some of the options your dentist might discuss include:

Analgesics: These are the most commonly used drugs for relief of toothache or pain following dental treatment. They includes aspirin, acetaminophen and anti-inflammatory drugs such as Ibuprofen. There is a separate category of ‘narcotic analgesics’ – such as those containing codeine – which are used for more severe pain.

Local anesthesia: Topical anesthetics are applied to mouth tissues with a swab to prevent pain on the surface level. They may also be used to soothe mouth sores. Injectable local anesthetics prevent pain in a specific area of your mouth during treatment by blocking the nerves that sense or transmit pain and numbing mouth tissues.

In other cases, your dentist many recommend sedation or general anesthesia.

Your dentist will discuss the best approach to suit your needs.

How sedation and general anesthesia can make your visit to the dentist easier

While local anesthetics are often used in dental treatment, there is sometimes a need for anti-anxiety agents – such as nitrous oxide – or sedatives to help people relax during dental visits.

Dentists may use these agents to induce “minimal or moderate sedation”.

In this case, the patient reaches a relaxed state during treatment but can respond to speech or touch.

Sedatives can be administered before, during or after dental procedures by mouth, inhalation or injection.

More complex treatments may require drugs that can induce “deep sedation”.

This reduces consciousness and causes a loss of feeling which helps to reduce both pain and anxiety.

Sometimes patients undergo “general anesthesia” where the drugs lead to a temporary loss of consciousness.

A dentist may recommend deep sedation or general anesthesia for certain procedures with children or with adults who have severe anxiety or for people who have difficulty controlling their movements.

While these techniques to control pain and anxiety are used to treat tens of millions of patients safely every year, it’s important that you let your dentist know anything that might affect your ability to benefit from them for example, tell them about any illnesses or health conditions, whether you are taking any medications and if you’ve had any problems with allergic reactions to medications.

What is plaque and how does it affect your teeth?

Plaque is a sticky film of bacteria that covers our teeth and, when we eat something, these bacteria release acids that attack the tooth enamel.

When these attacks are repeated over time, the enamel will break down and this will eventually lead to cavities.

When plaque is not removed through daily brushing and cleaning it hardens into calculus or tartar. When tartar collects above the gum line, brushing and cleaning between the teeth becomes more difficult.

The gum tissue can become swollen or may bleed. This is called gingivitis and it is the early stage of periodontal (gum) disease.

There are several steps you can take to protect yourself against this happening:

– Brush your teeth twice a day with fluoride toothpaste
– Clean between teeth daily with floss or an interdental cleaner
– Eat a balanced diet and limit the number of snacks between meals
– Visit your dentist regularly for professional cleanings and oral exams
– Ask your dentist about sealants – these are protective coatings that can be applied to the back teeth where decay often starts.

If you take steps to remove the plaque each day, you have a greater chance of avoiding tooth and gum problems.
