Clean Teeth, but without pressing too hard. Don't overpower, don't press the toothbrush when brushing them because it is very harmful. Use a brush with thin, soft strands to avoid scratching the tooth surface, and an abrasive-free toothpaste. Use circular brushing techniques or also gum-to-tooth sweeping techniques, not the opposite direction, so as not to cause gum recession.
