For sensitive gums, it is generally recommended to use a sonic toothbrush over an electric toothbrush. Sonic toothbrushes produce rapid vibrations that are gentler on the gums, reducing the risk of irritation or damage. The gentle cleaning action of a sonic toothbrush can help to effectively remove plaque and bacteria without causing discomfort to sensitive gums. However, it is important to consult with a dentist to determine the best option for your specific dental needs. **

No, a pilot in an airplane does not hear the sonic boom caused by their own aircraft. This is because the sonic boom is created by the shock waves produced when an aircraft travels faster than the speed of sound. These shock waves are left behind the aircraft and travel at the speed of sound, so the pilot would not hear them. However, pilots flying at supersonic speeds may hear the sonic booms produced by other aircraft flying at similar speeds. **

It is unlikely that one can completely avoid the tickling sensation of an electric sonic toothbrush through training alone. The sensation is caused by the rapid vibrations of the toothbrush, which can be difficult to completely desensitize oneself to. However, some individuals may find that they become more accustomed to the sensation over time with regular use. Additionally, experimenting with different brushing techniques and pressure may help to minimize the tickling sensation. **

The choice between a sonic toothbrush and a rotating toothbrush ultimately depends on personal preference and dental needs. Sonic toothbrushes use high-frequency vibrations to clean teeth and gums, while rotating toothbrushes have bristles that spin in a circular motion. Sonic toothbrushes are often preferred for their ability to reach deep between teeth and along the gum line, while rotating toothbrushes may be better for removing surface stains and plaque. It's important to consider factors such as sensitivity, gum health, and specific dental concerns when choosing between the two types of toothbrushes. **
