Top dam is a light-curing resin, which replaces the rubber dam (complete isolation) in some cases where relative gum isolation is sufficient.
More info


Top dam is the sales leader gingival barrier on the market due to its excellent sealing power, providing easy removal without irritating the gingival tissues.


• 1 syringe with 2g
• 3 applicator tips
• Available in the colors: blue, green, violet and pearl

Characteristics and Advantages

• Viscosity and thixotropy suitable for easy and perfect coverage of soft tissues without flowing into undesirable regions.
• Excellent sealing power.
• Minimal and perfect adherence to the gums.
• Does not come off the gum unless forced. Comes off in one piece when removing it.
• Does not irritate the gingival tissues.
• Variety of colors, enabling differentiation from the rubber sheet when used as an aid in sealing the rubber dam.


• It is indicated as a substitute for the rubber dam in order to protect the gingival tissue in cases of risk of irritation from contact with the products used in clinical procedures, such as tooth whitening with 35% hydrogen peroxide and as an adjunct in absolute isolation for better sealing of a cavity preparation or endodontic treatment.

Step by Step

Step 1

Dry the gums and teeth corresponding to the region to be protected.

Step 2

Apply a thin layer of the product (up to 1mm) on the gums and gingival papillae in such a way as to obtain full coverage and a good protection field for the procedure to be applied.

Step 3

Cure the resin using 20 to 30 seconds of light from a light-curing unit. Curing is recommended after application of the resin to prevent any possible irritation.

Step 4

Make sure the product covers the entire surface of the gums and if it is completely cured. To observe the posterior part of the papillae and gum use a clinical mirror, looking from the incisal to the cervical surface. Avoid testing it by forcing or trying to lift it because it could cause infiltration of the irritating substance.

Step 5

For removal of the product simply pull the barrier forward, and it should easily release in one or large pieces.


Is the gum protector easy to apply?

Yes. The gingival barrier is easy, comfortable and quick to apply and, of course, is much better than the rubber dam in different situations (see step by step application).

Does the Top dam layer need to be thick?

No. The layer may be thin. The important thing is to cover the gum sufficiently to protect the adjacent tissues.

Is the color of Top dam the same before and after light curing?

In principle, the color does not change after curing. However, after curing the product may appear to lose its shine.

What is the curing time of Top dam?

In cases where bleaching with the use of light is conducted, the curing time is short (20 seconds) because the curing is completed with the whitening process. In other cases, we recommend curing for a longer time.

Can laser light be used for curing Top dam?

Yes, it can. The gingival barrier cures with blue light. The dental surgeon should be careful with the power of the laser so as not to have a side effect from the intensity of the light.

Is Top dam adhesive?

Yes. To provide better sealing power, there may be slight adhesion to the gum.

Is Top dam easy to remove at the end of the procedure?

Yes. With the aid of an instrument (e.g. explorer) just pull it forward. It has a reasonably rigid structure to avoid fragmentation upon removal.

Could Top dam become detached during the clinical procedure?

No. During curing, it sticks to the gum, papillae or tooth. Detachment may only occur if there is mechanical force over it (lifting or accidental hitting).

Does the gingival protector cause any irritability or sensitivity?

Generally no. The patient may feel a slight sensitivity at the time of Top dam curing but that disappears at the end of the process. There may be cases of allergic reactions to the product, but these are exceptions.

Can the light-curing units cause sensitivity?

There is no relationship between sensitivity and the light curing devices, regardless of the distance.

During isolation with Top dam is it necessary to cover some millimeters of the cervical area of the teeth to be whitened?

Yes. The cervical area should be covered to prevent contact with the edge of the gun. Generally, 0.5 to 1 mm is sufficient.

Could Top dam compromise cervical whitening of covering 0.5 to 1mm?

Coverage from 0.5 to 1mm is necessary, otherwise sealing cannot be guaranteed. Whitening on the cervical area is not compromised because the peroxide ends up penetrating the tooth structure sufficiently.

Could Top dam replace and/or complement the rubber dam?

In some cases, yes. Top dam is a relative isolation and has advantages over the dam, such as ease of application, more comfort for the patient etc. However, it is not good for isolation against humidity.
