Definitions

  • the present invention relates generally to a cleaner and applicator for cleaning teeth. More specifically, the present invention relates to a formula and a single dose applicator to remove stains from the surface of a tooth.
  • teeth become stained over time from contact with coffee, tea, juice, tobacco, and other foods.
  • the first method requires one or more visit to a dentist's office and have the teeth professionally cleaned by a dentist.
  • the second method uses an at-home bleaching kit that the user can apply at home.
  • the third method uses whitening toothpastes and slowly whitens teeth over time with regular brushing of the teeth with the whitening toothpaste.
  • the first method is the most expensive but is the most effective of the three methods.
  • a chairside bleaching requires one or more visits to a dentist's office. Each visit may take from 30 minutes to one hour. During the chairside bleaching, the dentist will apply either a protective gel to the gum or a rubber shield to protect the oral soft tissues.
  • a bleaching agent is then applied to the teeth. Some procedures may use a special light, such as a laser light, to enhance the action of the agent.
  • This first method requires taking time off from work or regular daily activity to schedule one or more appointments with a dentist, travel to the dentist's office, and remain there for 30 minutes to one hour for the procedure, assuming there are no waiting, and paying a large sum of money for the procedure.
  • the second method is more economical than visits to a dentist's office.
  • the user may purchase an at-home bleaching kit over-the-counter from the local pharmacy or drug store to perform the whitening procedure himself at home.
  • These products contain peroxides to actually bleach the tooth enamel. Most of these products rely on percent carbamide peroxide as the bleaching agent.
  • Carbamide peroxide is generally available is several different concentrations such as 10%, 16%, and 22%. These products typically come in the form of a gel and are placed in a mouthguard. The actual application process varies. Some products are used for about twice a day for 2 weeks, and others are intended for overnight use for one to two weeks.
  • a dentist may provide a custom-fitted mouthguard if the at-home bleaching kit is purchased from the dental office.
  • This method has various side effects that may bother the user.
  • the teeth can become sensitive during the period when the user is using the bleaching solution.
  • Some user may experience soft tissue irritation-either from a mouthguard that doesn't fit properly or from solutions that may come in contact with the tissue.
  • the whitening effect from this method is gradual and requires constant contact with the bleaching agent for hours at a time.
  • This method also requires a delicate procedure of applying the bleaching agent in a generic mouth guard and inserting that mouthguard into the user's mouth for hours at a time. If the mouth guard is not custom fitted by a dentist, which is an expensive procedure, the mouth guard may be very uncomfortable to wear. Furthermore, a generic mouthguard may irritate the gum if improperly fitted.
  • the third method is the least effective but may be the least expensive. All toothpaste help remove surface stains through the action of mild abrasives. Some "whitening" toothpastes have special chemical or polishing agent that provide additional stain removal effectiveness. However, this method is the least effective and requires daily use over extended period of time.
  • One of the bleaching agent that have been experimented with is a relatively strong acid such as hydrochloric acid and phosphoric acid.
  • the acid can effectively remove the stains from the surface of the tooth.
  • this bleaching agent has not been successfully commercialized due to the highly corrosive nature of the acids and the difficulty of controlling the dosage and application of the acid. Even if the acids are contained in very small bottles, it is very difficult if not virtually impossible to accurately control the safe dosage and application of the acid to the tooth surface. Furthermore, a spill of even a small quantity of the acid will be very dangerous and difficult to clean-up. In addition, skin contact with the acid is highly likely with conventional application methods. BRIEF SUMMARY OF THE INVENTION
  • the present invention is a formula and a single dose applicator to remove stains from the surface of a tooth.
  • An object of the present invention is to provide a safe, simple, and effective means to effectively remove stains from the surface of a tooth.
  • Another object of the present invention is to provide an accurately pre-measured fo ⁇ nula in a disposable single-dose applicator for removing stains from the surface of a tooth.
  • Yet another object of the present invention is to provide a safe, simple, and effective means of removing stains from the surface of a tooth without making the tooth sensitive.
  • the tooth cleaner and applicator comprises of a tooth cleaning formula enclosed within a small elongated tubular container.
  • An applicator tip may optionally be affixed to the end of the small elongated tubular container.
  • the formula comprises of an acid selected from the group consisting of hydrochloric acid, phosphoric acid, and citric acid.
  • the small elongated tubular container is a single-dose disposable plastic container with a sealed end.
  • An optional protectant such as a base formula, a gel, a cotton strip, a plastic or rubber film, or glycerin may be applied to the gum and soft tissues around the teeth to protect them from the acid before or after application to prevent tooth sensitivity.
  • Figure 1 shows the preferred embodiment of the tooth cleaner and applicator.
  • Figure 2 shows the preferred embodiment of the tooth cleaner and applicator in the operating position.
  • the tooth cleaner and applicator comprises of a tooth cleaning formula 4 enclosed within a small elongated tubular container 1.
  • the small elongated tubular container 1 is a single-dose disposable plastic container with a sealed end 2.
  • the tooth cleaning formula 4 is disposed within the small elongated tubular container 1 near the sealed end 2.
  • a viscous substance 5 such as silicone is disposed between the open end of the small elongated tubular container 1 and the tooth cleaning formula 4 to prevent evaporation and contamination of the tooth cleaning formula 4.
  • An optional applicator tip 6 may be affixed to the open end of the small elongated tubular container 1.
  • An opening means 3 is positioned near the sealed end 2 of the small elongated tubular container 1 to enable opening of the small elongated tubular container 1 near the sealed end 2 to allow air to enter through the opening so as to release the tooth cleaning formula 4 through the open end of the small elongated tubular container 1.
  • the opening means 3 is a fracture line that will break open the small elongated tubular container 1 when the small elongated tubular container 1 is bent near the fracture line, as shown in figure 2.
  • the small elongated tubular container 1 is preferably made of a plastic material such as polypropylene or polyethylene.
  • the small elongated tubular container 1 is preferably similar to the container disclosed in US patent number 5,702,035, which is fully incorporated herein.
  • the small elongated tubular container 1 may also be similar to the containers disclosed in US patent application numbers 10/425,791 and 10/693,426, which are also fully incorporated herein.
  • the tooth cleaning formula 4 comprises of an acid selected from the group consisting of hydrochloric acid, phosphoric acid, and citric acid.
  • the tooth cleaning formula 4 comprises of 1% to 20% hydrochloric acid (HCl) with 5.4% being the most preferred.
  • the tooth cleaning formula 4 comprises of 5% to 50% phosphoric acid (H 3 PO 4 ).
  • the tooth cleaning formula 4 comprises of citric acid (C O H S O 7 ). All three acids may be used concurrently or the three different acids may be mixed in any desired ratio and combination with each other.
  • the tooth cleaning formula 4 may additionally contain a fragrance, a flavoring, a colorant, or glycerin.
  • the glycerin will increase the viscosity of the tooth cleaning formula 4 to control the application rate of the tooth cleaning formula 4. The higher the viscosity, the slower the rate of flow of the tooth cleaning formula 4 out of the elongated tubular container 1. By adjusting the viscosity, it is possible to control the rate of flow of the tooth cleaning formula 4 such that the tooth cleaning formula 4 will not simply run out of the elongated tubular container 1 and overflow the area of application.
  • An applicator tip 6 may optionally be affixed to the end of the small elongated tubular container 1.
  • the applicator tip 6 may be made of an absorbent material, such as cotton, foam, or sponge, or silicone rubber.
  • the applicator tip 6 has sufficient stiffness and roughness to effectively scrub the tooth surface.
  • a powder such as aluminum oxide (Al 2 O 3 ) or silicone carbide (SiC) is impregnated in the applicator tip 6 to further increase the effectiveness of the applicator tip 6.
  • the powder increases the effectiveness of tooth cleaning by providing an abrasive to increase the scrubbing effectiveness of the applicator tip 6 on the tooth surface.
  • the powder may also be provided in a separate small container to be used along with the applicator tip 6 of the small elongated tubular container 1.
  • the powder is retrieved from the small container by the applicator tip 6 after the tooth cleaning formula 4 is released into the applicator tip 6 to moisten it.
  • a protectant in the form of a liquid, gel, or powder, or a cotton strip, plastic shield, or rubber shield may be used to protect the gum and the soft tissues around the teeth.
  • the protectant may be glycerin.
  • the protectant may also be a base formula to neutralize the tooth cleaning formula 4.
  • the preferred base formula may be either sodium bicarbonate (NaHCOs) or sodium carbonate (Na 2 CO 3 ). Naturally, any other suitable base formula may be used.
  • the protectant is enclosed in a small elongated tubular container similar to the tooth cleaning formula 4 container, such as the container disclosed in US patent number 5,702,035.
  • the protectant may be contained in a separate compartment within the same elongated tubular container as the tooth cleaning formula 4, such as the container disclosed in US patent application number 10/693,426.
  • the base formula protectant may be applied either before or after the application of the tooth cleaning formula 4 to neutralize the tooth cleaning formula 4 on the gum and soft tissues around the teeth.
  • the tooth cleaner and applicator, the protectant in the form of a cotton strip, plastic shield, or rubber shield, and the base formula in a separate small elongated tubular container may be packaged in a kit in different combinations.
