Ultraviolet light is used to cure, or harden, composite fillings. White, tooth-colored fillings have a photo initiator within them that responds to ultraviolet light. The energy within the light causes the initiator to polymerize the composite material and harden it into its final configuration.Click to see full answer.

Why does my dentist use a UV light?
Why Fixed UV Light Disinfection for Your Dental Practice? Studies have confirmed that UVC light is an effective addition to manual cleaning efforts and can kill harmful pathogens quickly and efficiently. Exposure to UVC light for a specific length of time and intensity kills dangerous microorganisms.
How does UV light harden dental fillings?
"The light sends wavelengths of blue-violet light to the composite, which triggers hardening," says Alpesh Patel, a rising MCG School of Dentistry junior. "The light waves produce free radicals that activate the catalyst and speed up polymerization of the composite resin.
How do dentists harden fillings?
The dentist places composites in layers to fill the cavity completely. Putting them in layers allows the dentist to shape the to fit nicely in the teeth to prevent a change in your bite. The composite is “cured” in place using a bright ultraviolet light to harden the composite resins very rapidly.
Why do orthodontists use UV light?
Conclusions: UV light is more effective and tends to be more efficient than white light in the detection of fluorescent adhesive during orthodontic debonding. Although there are limitations, the use of UV LED lighting is a practical tool that aids in adhesive detection.
Is dental curing light harmful?
Background. Dental light-curing units (LCUs) are powerful sources of blue light that can cause soft-tissue burns and ocular damage.
Are dental curing lights safe?
Over exposure to blue light cure without protective measurements can induce apoptosis to the cornea, increased ocular inflammation and dryness of the eye. The short term risks associated with dental Lights cure is particularly low if safety measures are used.
Which type of dental filling is better?
A silver amalgam filling has been the most recommended dental filling for many years, dating back several generations. The biggest benefit to silver amalgam is that it tends to last much longer than various other forms of dental fillings, although the increase in dependability does come at a higher financial cost.
Can tooth decay continue after filling?
Unfortunately, tooth decay can still happen underneath a filling, especially if the filling has been cracked, worn, or otherwise damaged. In these cases, bacteria can enter your tooth and a new cavity can start again.
How many times can a filling be replaced?
There is no single number of how many times you can have a filling replaced. Usually, we will stop replacing the dental filling after the hole becomes too large. Once you have more filling material than natural tooth material your tooth no longer holds enough strength.
What is the blue stuff dentists put on your teeth?
Bite blocks are made out of blue or tooth colored material. They are used to help protect your brackets from your teeth or to help correct a deep bite or unlock your bite.
Why do dentists use blue light?
In dentistry, blue light is widely used for tooth bleaching and restoration procedures involving composite resin. In addition, many dentists use magnification loupes to enable them to provide more accurate dental treatment. Therefore, the use of light is indispensable in dental treatment.
How are fillings cured?
There are several materials that are curable by light. These lights can be Tungsten halogen, LED, plasma, and laser. Halogen and the LED are the most popular. A dental curing light that hardens a white tooth colored filling.
What does the blue light do to fillings?
This "blue wand" is a curing light. This light is used for polymerization of light-cured resin-based composites or, in other words, the white filling that we put in a tooth. There are several materials that are curable by light. These lights can be Tungsten halogen, LED, plasma, and laser.
How does a dental curing light work?
There are a wide variety of LCUs, and the technology has developed continually since photo-curing was first used in dentistry. Photopolymerization works by using light energy to activate a photoinitiator; a molecule that can absorb light and generate reactive species (free radicals) that initiate polymerization.
What is a UV light filling?
Composite resin is a mixture of plastic and glass or quartz. It's applied in layers which are cured using a UV light. They're used for filling cavities and repairing chipped or cracked teeth. Here are some of the benefits of composite resin: ●Can be matched to the exact color of teeth.
What does the blue light at the dentist do?
In dentistry, blue light is widely used for tooth bleaching and restoration procedures involving composite resin. In addition, many dentists use magnification loupes to enable them to provide more accurate dental treatment. Therefore, the use of light is indispensable in dental treatment.
Why do dentists use LED lights?
The majority of dentists today use LED curing lights because they don’t overheat like the halogen lights do .
How Does it Work?
When you have a cavity, your dentist removes tooth decay with a drill and prepares the tooth for a dental filling. The filling material, resin, is generally soft and can be moulded by biting down or by manipulating it with instruments. When the resin is exposed to this light, the material hardens and makes it strong enough for normal chewing. Resin can take anywhere from 20-60 seconds to harden using the dental curing light.
Is a laser tooth curing light dangerous?
Since it is not a laser, the dental curing light is not dangerous to the teeth and gums. Since it is very bright, it can put a strain on your eyes if you look at it too long. This is similar to the way your eyes strain if you look at the sun for too long. Dentists and assistants know not to look at the light for long periods of time.
What is the purpose of ultraviolet light?
Ultraviolet light is used to cure, or harden, composite fillings. White, tooth-colored fillings have a photo initiator within them that responds to ultraviolet light. The energy within the light causes the initiator to polymerize the composite material and harden it into its final configuration.
What is a curing light?
It’s a curing light. It is used as a catalyst to polymerize composite resins (white fillings). It is also used for certain cements or other materials. It falls under the blue light spectrum.
What happens if you don't get your teeth cleaned?
If you don't get your teeth cleaned regularly by a dental professional (twice a year is ideal unless you have a history of periodontal disease) you may develop periodontitis- and infection of the bone that holds your teeth in your head where it's good to keep them.
What does a dental margin tell you?
It removes debris when you want to examine teeth. We can detect faulty margins on fillings and crowns with it. It is used to give a point of reference where the area of need is on a tooth. It can tell u
Why do teeth shift?
Teeth have all kinds of fracture and craze lines in them from daily use and trauma. The most common reason I see fracture lines is from malocclusion. Due to the fact that teeth shift over a persons lifetime even a person that had previous orthodontics can have teeth shift. As a dental practitioner it can be difficult to determine when to send someone for treatment. It is not an inexpensive option and it does cause some additional trauma to the teeth and supporting structure as well as increased risk of decay and periodontal issues since teeth are harder to clean properly with ortho. It is also
