Sensitive gums could be a sign of inflammation, meaning there may be plaque buildup on the teeth or below the gumline. The Proclaim system, in combination with brushing, is designed to effectively and quickly clean those areas to reduce gum inflammation, gum bleeding, and plaque accumulation. Proclaim also includes a water pressure dial so you can start using Proclaim at a lower pressure that is comfortable for you, and slowly build up to the maximum pressure. If you experience extreme sensitivity during your normal oral care routine we recommend you check with your dental professional about what might be causing your sensitivity, and about using Proclaim.
