A dental varnish is a coating fluid for teeth, which is put on in slim layers and transformed to a steady, firm film by chemical or physical progression.
In dentistry, simply water- or solvent-based liquid systems are employed, as they facilitate easy, fast and consistent application on the surfaces to be treated.
- It is supposed to be Homogeneous quality
- Discharge of active material.
- Patient comfort
- Simple, secure application
- Good storage constancy
The Major Tasks of Dental Varnishes are:-
- Safeguard of the teeth from caries:-
To look after the teeth from caries through the discharge of active substances – fluoride or antimicrobial substances are used. Fluoride decreases the demineralization of dental enamel and antimicrobial substances fighting cariogenic bacteria.
- Enhancing the Esthetics of the tooth shade
Varnishes that have bleaching agents are spread over to eliminate discolorations or to whiten the teeth
- Desensitization of sensitive tooth collar
Desensitizing sensitive tooth necks can be attained by means of the formation of a mechanical block, i.e. a physical layer covering bare dentin tubule. This put off or minimizes any transmission of pain stimuli into the tubule via efficiently sealing them. A sustainable stop underneath the tooth surface is as a result perfect.
- Fluoride Varnishes
- Antimicrobial Varnishes
- Desensitizing Varnishes
- Tooth Whitening Varnishes
Based on Curing:-
- Physically Cured Varnishes
- Chemically Cured Varnishes
Fluoride Varnish is a protecting covering that is painted on teeth to avert CAVITIES. A fluoride varnish offer protection from demineralization or erosion.
- For moderate-high caries risk patients
- As a chief preventive measure
- As a treatment for hypersensitive teeth
- To reduce post operative sensitivity
- Used as a cavity liner
What Parents have to to Know
Healthy gums and teeth are essential to your child’s general health. Once your child has a tooth, your doctor may suggest that your child be given fluoride varnish treatments in the pediatrician’s office to aid prevent tooth decay.

You may be asked to grasp your child in your lap at the same time as you are placed knee-to-knee with the individual applying the varnish.
- First Fluoride varnish developed in Germany
- Yellow viscous material having 22,600 ppm fluoride as sodium fluoride in a neutral colophonium base (NaF Contains 2.2%fluoride)
- Duraphat has publicized caries diminution of between 30-40% in permanent dentition and 7-44% in the primary dentition
Contains a lower fluoride concentration than Duraphat (1.8% flouride) and has effectiveness equal to that of duraphat as a caries protective agent
- Clear polyurethane base product contain 7000 ppm fluoride (Silane flouride with 0.7%F in polyurethane base)
- It has a range of efficacy between 1% and 17% but its clinical efficiency is doubtful
5% NaF in alcoholic suspension of natural resins.
Techniques of Varnish Application
- Oral prophylaxis
- Teeth are dried out, but not separated with cotton rolls
- A total of 0.3-0.5 ml of varnish equal to 6.9-11.5 mg F is required to coat full dentition
- Application is made using single tufted small brush starting with proximal surfaces
- After application patient is made to sit with the mouth open for 4 minutes previous to spitting to allow Duraphet lay down on teeth
- Patient is ask not to rinse or drink whatever thing at all for one hour and not to eat anything solid but he/she can take liquids and semi solids till the next morning so that contact between varnish and tooth surface for about 18 hours uphold for extended interaction between fluoride and enamel.
Advantages of fluoride varnish over professionally used fluorides
- Simple to use and swift to apply
- Gels and foams entail the use of suction, air drying the teeth, trays that may prompt gag reflexes
- Harmless and posses a smaller amount of adverse reaction for the reason that only small amount is used.
- It does not necessitate the use of dental equipment or instruments
- Yellowish discoloration of teeth slowly fades
- Unwanted taste in mouth subsequent to application
- An antimicrobial protective varnish can decrease the bacteria and assist move the bacterial balance to a healthier level
- By reducing the bacterial tot up, an antimicrobial varnish can also reduce other difficulties caused by bacteria, for example inflammation of the gingiva
- Chlorhexidine thymol varnish is normally used antimicrobial varnish. It has antimicrobial action against all gram positive and gram negative microorganisms.
- kind of varnish indicated for the treatment of dentinal sensitivity
- Contraindicated in ulcerative gingivitis and stomatitis
Fluoraphat pro is a Dental Desensitising Varnish with Sodium Fluoride 5% and pleasing Melon Flavour which seals dentinal tubules efficiently.
Due to calcium fluoride deposits on the tooth surface a shield from acid assail is offered and the remineralisation is activated.
Fluoraphat pro present the option to close dentine tubules after cavity preparation and dentine tubules on sensitive root surfaces in an simple way.
In addition, it is not needed to dry out the tooth surfaces as Fluoraphat pro also stick on on wet surfaces very healthy.
– speedy desensitizing of hypersensitive dentine
– Sealing of dentinal tubules following cavity preparation
– closing of dentinal tubules on sensitive root surfaces

– safety from acid attacks
– Easy application even on drenched surfaces
– great aesthetics: white-transparent tooth colour
Tooth Whitening Varnishes
- A tooth whitening varnish has an oxidant, generally peroxide, which disperse into the tooth following the application of the varnish.
- Peroxide is uneven in the oral cavity. Their breakdown generate oxygen, which changes stains and discoloration into colorless compounds.
- The varnish has no or very slight of the active substance, thus there is no additional advantage to the varnish remaining on the tooth, and it is supposed to be simply detached.
