How do you pronounce the l sound? Do you know how to say the l sound? Put the front part of your tongue on the gum in your mouth, and let the air pass on both sides of your tongue, saying l.
What about the r sound? Can you speak the r sound? What is the difference between the l sound and the r sound?
When you say the r sound you should bend the front part of your tongue. However your tongue should not touch the roof of your mouth. And make the air pass on both sides of your tongue, saying r.

Are the expressions above grammatical? If you find unnatural expressions, would you correct them?
Can we use 'alveolar ridge' instead of 'gum'?
The expressions are grammatical. "Alveolar ridge" is seldom used except by speech teachers or specialists.
The word "gum" in this context refers to the tissue that holds the teeth in place. I think you're referring to the roof of the mouth (the more common expression for alveolar ridge).
Yes, the expressions above are grammatical. However, there are a few improvements that can be made:
1. Pronunciation of the "l" sound: To pronounce the "l" sound correctly, place the tip of your tongue against the alveolar ridge, which is the bumpy area just behind your upper teeth. Then, let the air pass alongside your tongue while voicing the "l" sound.
2. Pronunciation of the "r" sound: To pronounce the "r" sound properly, slightly curl the tip of your tongue upwards without touching the roof of your mouth. Allow the air to pass on both sides of your tongue while voicing the "r" sound.
Yes, you can certainly use "alveolar ridge" instead of "gum" to refer to the bumpy area behind the upper teeth. Using the term "alveolar ridge" is a more precise description of where the tip of the tongue should be placed for the "l" sound.
