Is it safe to use mouthwash daily or does it cause ulcer in the mouth? Which is a good brand?

Ans: If a mouthwash causes ulcers it's quite likely you're allergic to one of its ingredients. So you might want to try out another brand/compositionThere's certainly no harm in using a compatible mouthwash daily

Hi Doctor, I’ve been hearing a lot about mouthwash and floss lately, and I’m confused about whether I really need to use it. I brush regularly 2 times, but sometimes I feel like my breath isn’t as fresh as I’d like it to be. I also want to keep my teeth strong and prevent any issues with bacteria. Can you tell me if mouthwash is necessary even if I’m already brushing and flossing? If yes, which type of mouthwash would be best for someone like me? I’ve heard that it can sometimes cause mouth sores or sensitivity, so I want to make sure it’s safe for me.
Ans: Hello
I'm happy to know you brush and floss regularly. Please continue to do so.
While poor oral hygiene is the leading cause of bad breath, it is definitely not the only cause. Please be informed that it can be caused by various other factors, too.

Here are some of the most common causes of bad breath, also known as HALITOSIS.

Oral Health Issues
1. _Poor oral hygiene_: Infrequent brushing and flossing can lead to the buildup of bacteria, plaque, and tartar, causing bad breath.
2. _Gingivitis and gum disease_: Inflammation and infection of the gums can cause bad breath.
3. _Tooth decay and cavities_: Bacteria in the mouth can break down food particles, especially sugars, and release volatile sulfur compounds (VSCs) that cause bad breath.

Food and Drinks
1. _Onions and garlic_: These foods contain sulfur compounds that can be released in the mouth and cause bad breath.
2. _Coffee and tobacco_: These substances can dry out the mouth, leading to an increase in bacteria and VSCs.
3. _Spicy or acidic foods_: Foods like citrus fruits, tomatoes, and spicy dishes can irritate the mouth and cause bad breath.

Medical Conditions
1. _Diabetes_: Uncontrolled diabetes can lead to dry mouth, which can contribute to bad breath.
2. _Gastroesophageal reflux disease (GERD)_: Stomach acid can flow up into the mouth, causing bad breath.
3. _Sinus infections and respiratory issues_: Postnasal drip and respiratory infections can cause bad breath.
4. _Kidney disease and liver disease_: These conditions can cause a buildup of toxins in the body, leading to bad breath.

Lifestyle Factors
1. _Smoking and tobacco use_: Tobacco products can dry out the mouth and cause bad breath.
2. _Alcohol consumption_: Excessive alcohol consumption can lead to dry mouth and bad breath.
3. _Medications_: Certain medications, such as antidepressants, antihistamines, and decongestants, can cause dry mouth and bad breath.
4. _Hormonal changes_: Hormonal fluctuations during menstruation, pregnancy, or menopause can lead to bad breath.

Other Factors
1. _Dry mouth_: A lack of saliva can contribute to bad breath.
2. _Mouth breathing_: Breathing through the mouth instead of the nose can dry out the mouth and cause bad breath.
3. _Poor digestion_: Undigested food particles in the stomach can be released into the mouth, causing bad breath.


If you're concerned about bad breath, it's essential to consult your dentist so that he can examine your teeth and gums thoroughly to rule out local factors and address any underlying medical conditions.

Mouthwashes definitely help by keeping the oral bacteria under control. At least temporarily. They mask mouth odours and give you a feeling of freshness.
But the root cause of the problem still needs to be identified and suitably treated. Also, please note that mouthwashes are not a substitute for regular brushing and flossing.
Your dentist will guide you on what mouthwash suits you best depending on your lifestyle, oral hygiene and medical history.
Meanwhile, here are some good attributes to look for in a mouthwash:

Active Ingredients
1. _Antibacterial agents_: Chlorhexidine, triclosan, or essential oils (e.g., tea tree oil) to combat bacteria and plaque.
2. _Anti-inflammatory agents_: Ingredients like aloe vera or chamomile to reduce gum inflammation.
3. _Antifungal agents_: Ingredients like domiphen bromide to combat fungal infections.
4. _Fluoride_: To strengthen tooth enamel and prevent decay.

Additional Benefits
1. _Anti-plaque and anti-gingivitis properties_: To help prevent the buildup of plaque and reduce the risk of gingivitis.
2. _Bad breath prevention_: Ingredients like chlorine dioxide or zinc to help eliminate volatile sulfur compounds (VSCs) that cause bad breath.
3. _Sensitivity relief_: Ingredients like potassium nitrate or strontium chloride to help desensitize nerves and provide relief from tooth sensitivity.
4. _Whitening agents_: Mild abrasives or hydrogen peroxide to help remove surface stains and whiten teeth.

Safety and Comfort
1. _Alcohol-free_: To avoid drying out the mouth and reducing saliva production.
2. _Sugar-free and artificial sweetener-free_: To make the mouthwash suitable for people with dietary restrictions or preferences.
3. _pH balanced_: To ensure the mouthwash doesn't disrupt the natural pH balance of the mouth.
4. _Gentle and non-irritating_: To minimize the risk of mouth irritation, especially for people with sensitive teeth or gums.

Hello, I am currently in Class 12 and preparing for JEE. I have not yet completed even 50% of the syllabus properly, but I aim to score around '110' marks. Could you suggest an effective strategy to achieve this? I know the target is relatively low, but I have category reservation, so it should be sufficient.
Ans: With category reservation (SC/ST/OBC), a score of 110 marks is absolutely achievable and realistic. Based on 2025 data, SC candidates qualified with approximately 60-65 percentile, and ST candidates with 45-55 percentile. Your target requires scoring just 37-40% marks, which is significantly lower than general category standards. This gives you a genuine advantage. Immediate Action Plan (December 2025 - January 2026): 4-5 Weeks. Week 1-2: High-Weightage Chapter Focus. Stop trying to complete the entire syllabus. Instead, focus exclusively on high-scoring chapters that carry maximum weightage: Physics (Modern Physics, Current Electricity, Work-Power-Energy, Rotation, Magnetism), Chemistry (Chemical Bonding, Thermodynamics, Coordination Compounds, Electrochemistry), and Maths (Integration, Differentiation, Vectors, 3D Geometry, Probability). These chapters alone can yield 80-100+ marks if practiced properly. Ignore topics you haven't studied yet. Week 2-3: Previous Year Questions (PYQs). Solve JEE Main PYQs from the last 10 years (2015-2025) for chapters you're studying. PYQs reveal question patterns and difficulty levels. Focus on understanding why answers are correct, not memorizing solutions. Week 3-4: Mock Tests & Error Analysis. Take 2-3 full-length mock tests weekly under timed conditions. This is crucial because mock tests build exam confidence, reveal time management weaknesses, and error analysis prevents repeated mistakes. Maintain an error notebook documenting every mistake—this becomes your revision guide. Week 4-5: Revision & Formula Consolidation. Create concise formula sheets for each subject. Spend 30 minutes daily reviewing formulas and key concepts. Avoid learning new topics entirely at this stage. Study Schedule (Daily): 7-8 Hours. Morning (5:00-7:30 AM): Physics concepts + 30 PYQs. Break (7:30-8:30 AM): Breakfast & rest. Mid-morning (8:30-11:00): Chemistry concepts + 20 PYQs. Lunch (11:00-1:00 PM): Full break. Afternoon (1:00-3:30 PM): Maths concepts + 30 PYQs. Evening (3:30-5:00 PM): Mock test or error review. Night (7:00-9:00 PM): Formula revision & weak area focus. Strategic Approach for 110 Marks: Attempt only confident questions and avoid negative marking by skipping difficult questions. Do easy questions first—in the exam, attempt all basic-level questions before attempting medium or hard ones. Focus on quality over quantity as 30 well-practiced questions beat 100 random questions. Master NCERT concepts as most JEE questions test NCERT concepts applied smartly. April 2026 Session Advantage. If January doesn't deliver desired results, April gives you a second chance with 3+ months to prepare. Use January as a practice attempt to identify weak areas, then focus intensively on those in February-March. Realistic Timeline: January 2026 target is 95-110 marks (achievable with focused 50% syllabus), while April 2026 target is 120-130 marks (with complete syllabus + experience). Your reservation benefit means you need only approximately 90-105 marks to qualify and secure admission to quality engineering colleges. Stop comparing yourself to general category cutoffs. Most Importantly: Consistency beats perfection. Study 6 focused hours daily rather than 12 distracted hours. Your 110-mark target is realistic—execute this plan with discipline. All the BEST for Your JEE 2026!

Dear Sir/Madam, I am currently a 1st year UG student studying engineering in Sairam Engineering College, But there the lack of exposure and strict academics feels so rigid and I don't like it that. It's like they don't gaf about skills but just wants us to memorize things and score a good CGPA, the only skill they want is you to memorize things and pass, there's even special class for students who don't perform well in academics and it is compulsory for them to attend or else the student and his/her parents needs to face authorities who lashes out. My question is when did engineering became something that requires good academics instead of actual learning and skill set. In sairam they provides us a coding platform in which we need to gain the required points for each semester which is ridiculous cuz most of the students here just look at the solution to code instead of actual debugging. I am passionate about engineering so I want to learn and experiment things instead of just memorizing, so I actually consider dropping out and I want to give jee a try and maybe viteee , srmjeee But i heard some people say SRM may provide exposure but not that good in placements. I may not be excellent at studies but my marks are decent. So gimme some insights about SRM and recommend me other colleges/universities which are good at exposure
Ans: First — your frustration is valid

What you are experiencing at Sairam is not engineering, it is rote-based credential production.

“When did engineering become memorizing instead of learning?”

Sadly, this shift happened decades ago in most Tier-3 private colleges in India.

About “coding platforms & points” – your observation is sharp

You are absolutely right:

Mandatory coding points → students copy solutions

Copying ≠ learning

Debugging & thinking are missing

This is pseudo-skill education — it looks modern but produces shallow engineers.

The fact that you noticed this in 1st year already puts you ahead of 80% students.

Should you DROP OUT and prepare for JEE / VITEEE / SRMJEEE?

Although VIT/SRM is better than Sairam Engineering College, but you may face the same problem. You will not face this type of problem only in some top IITs, but getting seat in those IITs will be difficult.
Instead of dropping immediately, consider:

???? Strategy:

Stay enrolled (degree security)

Reduce emotional investment in college rules

Use:

GitHub

Open-source projects

Hackathons

Internships (remote)

Hardware / software self-projects

This way:

College = formality

Learning = self-driven

Risk = minimal
