As we age, the risk of dental diseases increases. Our teeth, mouth and gums are put through a lot throughout a lifetime. Chewing, gnashing and grinding, smoking, eating sugar and sticky foods, poor diets and medications and a decrease in dental care can all take their toll.

All of these factors can increase the chances that as seniors, we’ll have to deal with oral health problems. Seniors are particularly at risk of developing the following oral health conditions. 

Gum Disease

The bacteria found in plaque and tartar can cause gum disease, which can contribute to a whole host of problems for your mouth and gums. Also called periodontal disease, early signs of gum disease include red irritated gums and bleeding when you floss or brush your teeth near the gum line.

Gingivitis is an early sign of gum disease. A buildup of bacteria where the gums meet the teeth causes the gums to become inflamed. Left untreated this can develop into periodontitis, which is more serious. Periodontitis damages the tissues of the gum and the bones that support the teeth.

Gum disease can:

• cause discomfort and make it harder to chew
• effect a senior’s immune system
• cause bad breath
• result in irreversible bone loss

Seniors are at increased risk of gum disease due to already lowered immune systems and decreased mobility which can make it hard to brush their teeth and gums thoroughly.

Dry Mouth

A dry mouth might not sound like a big concern, but it can lead to all sorts of oral health issues. A lack of saliva in the mouth increases the risk of cavities, contributes to digestion issues, and increases the chance of an oral infection. 

Saliva is essential for washing away plaque, food particles, and sugars. Without a good saliva flow, acids, plaque and bacteria can build up in the mouth. These can eat away at the delicate enamel on our teeth and cause cavities.

Although our mouths dry naturally a little as we age, the number one contributor to dry mouth in seniors is medication. Many medications list dry mouth as a possible side effect. Encouraging seniors to drink more water, and avoid sugary foods and drinks, will help. Sugar-free lozenges can help stimulate saliva production which naturally rinses out the mouth.

Tooth loss

Some people may think that losing teeth is a natural side effect of getting older. However, this doesn’t have to be the case. Being proactive about your oral health and adopting good hygiene habits will ensure your natural teeth last a lifetime. Unfortunately, untreated signs of gum disease, cavities, old dental work, and general poor health can contribute to tooth loss.

We only get one set of teeth so it’s important that we look after them.

What can seniors do to prevent these dental issues?

It’s not inevitable that we’ll lose our teeth, or get gum disease as we age. However, seniors should be aware that they need to be vigilant about their oral hygiene, even more so than when they were younger. Unfortunately, a loss of mobility or declining health can make it even harder for seniors to create healthy oral habits.

If a senior in your family is in a rest home or receives in-home care, talk to the primary carer about setting up a routine that is proactive about their tooth health. It’s a good idea to buy an electric toothbrush rather than a manual one, as these are more effective at getting rid of plaque. Most modern electric toothbrushes also come with two-minute timers, making it easier for seniors to know whether they have brushed for long enough.

Here are some habits you can talk to seniors and their primary carers about:

• Seeing their dentist regularly (regardless of oral health symptoms)
• Brushing and flossing every morning and night
• Using an electric toothbrush to make brushing easier
• Avoiding smoking, and eating too much sugar
• Checking their medications for side effects of dry mouth
• Increasing their daily water consumption

Regular checkups are the best way to maintain and monitor oral health as we age. If you need to book an appointment with a dental health professional click here.

Imagine if rather than getting a filling to fix tooth decay, you could get a whole new tooth! While it might sound like science fiction, dental researchers at the Harvard School of Engineering and Applied Science have actually created new teeth within a laboratory setting.

Researchers use lasers to stimulate stem cells to form dentin inside the mouth of real test subjects.

What does this mean for the future of dentistry?

 This breakthrough in dental research means instead of placing a filling in your tooth, dentists may actually be able to grow you a whole new tooth.

Fixing cavities with fillings means that dentists often have to destroy part of your tooth. The decay needs to be removed by drilling a hole and the hole repaired with a filling. Overall, fillings do weaken the structural integrity of the tooth. To be able to grow an entirely new, healthy and strong tooth would be an amazing alternative.

How does regenerating teeth work?

Researchers have been trying to recreate tooth material using stem cells for years. However, until now, they have never succeeded in using stem cells outside of a laboratory setting.

This new research is different as researchers have generated dentin inside the mouths of patients. The researchers used lasers and growth factors to encourage stem cells in the mouth to grow into dentin.

Researchers drilled into teeth to access the stem cells found in the molars. These cells were exposed to low-level lasers, and dental crowns were then put over their teeth. After 12 weeks the researchers found that the dentin in the teeth was successfully regrowing.

What is dentin and why is it important?

Dentin is a hard material that makes up part of your tooth. Although it’s less well known than pulp and enamel, dentin is very important as it makes up the majority of the structure of the tooth. Dentin is the layer between the enamel and the pulp.

How long will it take for teeth regeneration to become viable?

Science is still in its early days which means traditional fillings will be the norm for the foreseeable future. However, scientists are excited by the possibility that tooth regeneration will one day become the norm.

It’s also likely that there will always be a place for treating cavities with fillings. Regenerating new teeth may be costly and currently, the procedure takes a long time. The research will also need to undergo a lot of scrutiny and health checks to make sure it is safe for humans. So far, research has only been carried out (albeit successfully) on rats.

Since there’s no telling when tooth regeneration will become an option for treating tooth decay, you should always look after your teeth as best you can. You can always prevent cavities from forming. When it comes to cavities, prevention is always better than a cure.

How can I avoid cavities?

 Cavities are permanent damage caused to the surface enamel of your teeth. Tooth decay can be caused by sugar, mouth bacteria and plaque buildup on your teeth. To prevent cavities from forming there are several healthy habits you can adopt.

• Adopt a regular cleaning routine. Brush twice a day and floss between your teeth regularly. Brush your teeth for at least two minutes every time you brush.
• Brush with fluoride toothpaste. Fluoride helps to build up the strength of your tooth enamel.
• Avoid sipping sugary drinks. Sugars can cause an increase in acid in the mouth which attacks the enamel of your teeth. Cut down on soft drinks, energy drinks and adding sugars to tea and coffee. Sipping sugary drinks throughout the day can create the perfect breeding ground for acid and bacteria.
• Avoid foods that get stuck in your teeth. Nuts and chips can be bad for your teeth as they get stuck easily behind and between teeth.
• Visit your dentist regularly. Plaque can build up in hard-to-reach places in the mouth. Seeing your dentist regularly will ensure that all parts of your teeth are taken care of.

If you have tooth decay, your dentist may ask you whether you want an amalgam or composite filling. In both cases, your dentist will treat your teeth by removing any decay and fitting you with a fling. However, amalgam and composite fillings are different in appearance, materials, and overall performance.

Here’s everything you should know about choosing the right filing for your mouth.

What are amalgam fillings?

If you’ve never heard of amalgam fillings before, you will have seen them. Amalgam fillings are usually referred to as silver fillings and these are very common in older dental patients. In fact, dentists have used amalgam to treat cavities for around 150 years.

Amalgam fillings get their silver colour from the materials they are made from — usually silver, tin, copper, and mercury.

What are the key properties of amalgam fillings?

Amalgam fillings have been the go-to option of dentists for years. They are:

• Less expensive than composite fillings 
• Durable and long-lasting 
• Harden quickly makes them quick to fit in place 

What are the pros and cons of amalgam fillings?

There are lots of benefits to having silver amalgam fillings. These filings:

• Can last for over a decade with proper dental hygiene habits and care 
• Are strong and can easily fill large cavities within a tooth 
• Have a lower price point and are more affordable than composite filings 
• Harden quickly which makes treatment less stressful for anxious patients 

While there is nothing wrong with having amalgam fillings, there are a few reasons why dentists may prefer a composite filling instead.

• Amalgam fillings are very noticeable even when fitted onto the back teeth. 
• Patients with metal allergies may have a bad reaction to the metals. 
• Amalgam fillings sometimes require more of the tooth structure to be removed. 
• Amalgam fillings expand and contract with exposure to some temperatures. This can cause fractures in the tooth. 
• Amalgam fillings are made with 50% mercury. While this is generally low enough not to cause toxicity, mercury is still a toxic material. 

What are the key properties of composite fillings?

Composite fillings blend in with the colour of the tooth and are made from a polymer-based resin that is free from mercury.

• They are often used as a long-term solution for small and medium filings 
• They may not be an appropriate long-term solution for very large cavities. Porcelain fillings or a full crown are sometimes used instead. 

What are the pros and cons of composite fillings?

• Composite resin does not last as long as amalgam and has a shelf life of around 5 years. 
• They are usually more expensive than amalgam fillings. 
• They can take longer to fit in the mouth than amalgam fillings as the composite resin is placed in layers into the mouth. 

These might all sound like good reasons not to get a composite filing, but there are a few major reasons why some dentists prefer composite.

• Composite does not expand or change in size and won’t cause teeth to crack.  
• They are virtually undetectable. Composite blends in with the colour of your tooth. 
• Dentists don’t have to remove as much of the tooth as composite fillings bond to the tooth. This means the tooth is stronger as it has more structure to provide support.   
• Composite resin is completely nontoxic. 

At Dental Gentle we prefer to use composite fillings as they are safer, non-toxic, and won’t compromise the structural integrity of the surrounding tooth. You also won’t have to worry about your fillings being visible when you open your mouth.
