Dental white fillings

Posted by Dental News Team On October - 22 - 2009

Plastic fillings – are they worth the cost?

kunststofffullungWhite fillings are in ever greater demand – but they are not always a good idea! People are sick of silvery mercury fillings (amalgamate), people want to look good, and this includes having a perfect set of teeth. Many people are now getting their amalgamate fillings replaced by plastic fillings – called composite fillings.

Composite fillings do not work that well in side teeth, a fact which many people do not know! Even manufacturers warn that these fillings should only be used to correct surface defects, since teeth do not react well to them. The tooth nerve often dies when this type of filling is used, leading to a root canal treatment.

Patients who get their amalgamate fillings replaced by plastic are in for a bumpy ride. The fillings consist of tiny building blocks called monomers. As soon as a dentist shines a lamp on the filling, these little monomers start to connect – like Lego blocks, a process called polymerisation, which results in polymers – larger building blocks. But these plastic structures are not stable enough to hold up under chewing, so little „Lego blocks“ – monomers – start to separate. These free-floating monomers are very toxic, they invade the tooth nerve, and the nerve dies.

You do not feel the pain right away, it may take years for the   „dead“ tooth to start making trouble, so patients do not always attribute this problem to the plastic filling. Some patients experience problems immediately after the plastic is inserted, such as problems when chewing, pressure, excessive sensitivity to heat or cold.

keramikinlayWhile some dentists specialize in this type of filling and use a coffer dam, special covers and layering methods to prevent complications, but plastic fillings still end up costing about as much as a ceramic inlay. But ceramic inlays are much better for your teeth than composite fillings – assuming the inlay is inserted correctly.

White teeth may be more trouble than they are worth!

Think about what you’re doing. If you invest in your teeth, then be sure to use goods materials – gold, titanium or ceramics! Or develop a better brushing technique, because if you have poor brushing habits then you will need fillings someday.”

Water irrigator to clean teeth

Posted by Dental News Team On October - 21 - 2009

Many doctors still wrongly advise against using an oral irrigator!

Whether you use an oral irrigator made by Braun, Panasonic,  Waterpik, or any other manufacturer – regular use keeps your mouth healthy!

mundduscheDoctors who are not very knowledgeable about micro-biology argue that an oral irrigator washes bacteria deeper into the gum pockets. While this may sound obvious, this is actually false. First of all, bacteria can move: they have cilia, flagella which help them move around pretty quick! Second,  bacteria are not dangerous in and of themselves!

Parodontitis and also cavities are actually caused by plaque.  Plaque is organized like a little city, there are bacteria which specialize in adhering to the teeth. Other bacteria gnaw at the teeth while others are mainly responsible for transporting nutrients. Mature plaque is organized like an ant heap.

It takes mature plaque 24 hours to form, after which you run the risk of developing parodontitis and/or cavities. The longer you wait before removing the plaque, the harder it gets to remove.

You should make it a habit to remove plaque at least every 24 hours,but using a toothbrush you can only do that above the gums, while the oral irrigator also reaches the areas just below the gums – in the sulcus, and also between the teeth.

Used once a day in combination with regular brushing, the oral irrigator helps to keep your mouth healthy! Do not be afraid if your gums start to bleed a little and hurt at the beginning, this will stop eventually, just keep cleaning!

Oral hygiene before bleaching?

Posted by Dental News Team On October - 21 - 2009

Does cleaning matter before bleaching?

Usually, yes!

When bleaching, the gums should not be inflamed, since inflamed gums bleed easily!
Blood may react with bleaching gel, moreover the gel is diluted and starts flowing uncontrollably around the mouth.

If you have a plaque problem on the insides of your teeth, or if you are a heavy smoker you should have your teeth cleaned before you undergo bleaching!

You should also go to a dentist if your gums are dark red instead of pale pink and the papilla are swollen – you may have parodontitis!

zahnfleischentzuendungCheck whether your gums are inflamed or healthy:
If your gums are pale pink and dimpled like an orange then your gums are healthy, and if you have very little or no plaque on the insides of your lower teeth, then you can have bleaching done right away.

How much does it cost to get bleaching done by a dentist?

Professional tooth whitening (bleaching) by a dentist costs between 200€ to 900€ in Central Europe.

Tea, coffee, red wine, tobacco, cola and natural ageing makes teeth darker or spotty. Bleaching can make your natural teeth whiter without complications.

Does bleaching damage the enamel or the teeth?

bleaching-vergleichsbild1Professional whitening is performed using active oxygen, which decolorizes the pigments found in the teeth. None of the enamel is removed, ground away or dissolved.

A glass of freshly squeezed orange juice is more liable to damage the enamel than professional bleaching.
Bleaching compared – before and after. If you brush your teeth after eating sour food or fruits, this may rub off some of the enamel, as certain foods can soften up the enamel.

After eating, you should always wait at least half an hour before brushing your teeth – then you’ll always have something to smile about!

Saliva test for cavity prevention?

Posted by Dental News Team On October - 20 - 2009

Saliva tests are used to detect bacteria (S.mutans and lacto-bacteria) taking into account the rate of flow of saliva and buffer capacity, in order to find patients with a higher risk of developing cavities!

speicheltestSaliva testing – a success story?
Not really, although you periodically read or hear about saliva testing for cavity prevention.

Saliva tests are commonly used in drug testing and crime investigation – but not in dentistry!

Individually administered tests exhibit a high rate of fluctuation, and cannot differentiate among children with high or low risk.

The good news last – regular visits to the dentist and good dental hygiene can prevent cavities!

Learn more about cavities, etc – in the first video lexikon!

The importance of side teeth

Posted by Dental News Team On October - 19 - 2009

Many people have missing side teeth. Most are not really bothered by this: what matters is that the front teeth  –  the window display – are in good condition!

This is a big mistake, since the side teeth are very important, they protect the jaw and the front teeth from excessive strain …

-

Missing side teeth can lead to headaches, jaw pain and even back pain due to overloading and overuse.

Here you can see a cross-section of a jaw with a complete set of teeth, and the  masseter, one of many chewing muscles. The masseter is highlighted in red.

masseter_kauebene-150x150When this muscle contracts, the lower jaw in pressed against the upper jaw. The teeth touch at the occlusion surface and the lower jaw comes to a stop because of the side teeth.
There is a definite gap between the jaw link head and socket.

By providing support, the side teeth protect the jaw from excessive chewing pressure. This mechanism is further reinforced as the side teeth touch before the front teeth do. The lower jaw rotates away from the joint, and the side teeth act as a hypomochlion (=angle point) and protect the jaw.

-

masseter_zahnlosIf the side teeth are missing, or the occlusion surface is decreased because of uneven teeth, then the masseter pushes the lower jaw more towards the base of the cranium, and the joint gap disappears. The jaw is overstrained, which in time can lead to slight pain or even necessitate operations on the jaw.
-

It is therefore crucial to replace teeth, not only front teeth for aesthetic purposes, but also side teeth! Replacing side teeth keeps you healthy. Moreover, front teeth tend to be overused if there are not enough side teeth, which makes bone recede and eventually leads to loss of front teeth! -

-

A partial denture can be used to replace side teeth, implants are not always necessary – the main thing is that you can chew on the side!
