Patent number: 10912717Abstract: A tooth whitening method uses an application device having a reservoir containing an oxidizing composition comprising a fluid carrier and an oxidizing agent, an applicator member in fluid communication with the reservoir, and a dispensing mechanism for moving contents of the reservoir into the applicator member. The oxidizing composition is dispensed into the applicator member by actuating the dispensing mechanism and is applied to one or more teeth in an oral cavity. Then, a sealant composition is applied to the teeth having the oxidizing agent thereon to form a coating that resists moisture contamination of the previously applied oxidizing agent. One embodiment uses an oxidizing composition with a viscosity less than 150 cps that is absorbed in a porous material in the device reservoir, from which it is introduced by capillary action into a porous applicator member.Type: GrantFiled: November 12, 2018Date of Patent: February 9, 2021Assignee: ORACEUTICAL LLCInventor: R.

Patent number: 9775790Abstract: A tooth whitening method applies a light transmitting oxidizing composition to teeth in an oral cavity, after which a hand-held LED light source with a light transmitting lens and a cup forming a chamber having an open end is moved over the teeth so that the cup distributes the oxidizing composition while the teeth are exposed to light transmitted through the lens. This not only ensures intimate contact of the teeth with the oxidizing composition, but also maintains a more or less constant spacing between the light source and the tooth surfaces for optimum results. A sealant is then applied to the teeth to resist moisture contamination of the oxidizing composition.Type: GrantFiled: November 17, 2014Date of Patent: October 3, 2017Assignee: Oraceutical LLCInventor: R.

Patent number: 9320580Abstract: A hand-held, ergonomic instrument with an LED that emits actinic light in visible wavelengths mounts a replaceable applicator cup with a reservoir for a tooth whitening composition held in place against a user's tooth during a whitening procedure. Actinic light is directed onto the tooth surface through a window in the cup and the tooth whitening composition substantially without attenuation, delivering at least about 100 milliwatts per square centimeter of light energy to the tooth surface. The cup includes a rigid body for mounting the cup to the instrument and an opaque flexible sleeve molded in place over the outside of the body to form a seal with the tooth surface and prevent exposure of soft mouth surfaces to the actinic radiation during a whitening procedure. A safety switch disables the LED when the applicator cup is not in contact with a tooth surface.Type: GrantFiled: April 21, 2013Date of Patent: April 26, 2016Assignee: Oraceutical LLCInventor: R.

Publication number: 20140011163Abstract: A vibratory fluid dispensing instrument holds a rheologically non-Newtonian (shear-thinning) liquid, gel, cream, or paste therapeutic composition in a container section of a disposable applying device from which the composition is manually dispensed into an applicator brush for application to one or more surfaces in an oral cavity. The instrument includes a vibratory appliance mounted to the device and mechanically coupled thereto to enable application of the composition in conjunction with mechanical energy that reduces the viscosity of the composition due to vibratory shear forces and thereby leads to better penetration of the composition into hard and soft tissue surfaces. The vibratory appliance can be separate from the applying device so that it can be removed from an applying device after the container section is empty and reused with a replacement applying device.Type: ApplicationFiled: July 3, 2013Publication date: January 9, 2014Inventor: R.
